JEEP 1/4-TON TRAILERS

Jeep Trailers
There are 4 models of what are commonly referred to as Jeep (cargo)Trailers.

  1. The WWII Military MBT and T-3 Jeep Trailers
    • T3 - built by American Bantam Car Co,. Butler, PA
    • MBT - made by Willys-Overland Motors Co, Toledo, Ohio
    • There were a few other small contracts handed out in 1945 to other lesserknown companies who copied the Bantam T-3 design
      1. GemcoEng. & Mfg. Co. Inc. (T-1 Trailer)
      2. PacificCar & Foundry Co., Renton, WA

  2. The Post-War (WW2) Civilian Jeep Trailers
  3. The Korean War vintage M-100 Military Jeep Trailers
  4. The Vietnam War era M-416 Military Jeep Trailers
The4 Jeep cargo model series are very similar in design, size, and construction.

Trailer, 2 Wheel, 1/4 Ton, MB-T (Willys) and T3 (Bantam) (G-529) The World War II jeeps (Willys MB and Ford GPW) used the 1/4 ton MB-T trailer manufactured by Willys or the nearly identical T3, made by Bantam. The post-war M-100 1/4 ton trailer was very similar, but set up for the 24 volt M-series vehicles. Approximately 60,000 of the Willys MB. Bantam also produced a civilian trailer based on the WW2 design. The example opposite is of the model T3-C and has the serial no. It was restored by Mark Harpootlian, Southfield, Michigan USA and he would love to hear from you if.

Your trailer does seem to be a Bantam.with the ACM number of '116858' it would be too late to have been A Willys and too early to have been one of the other mfgers I believe. The USA on the rear is not original to that trailer and would be from an August 1943 Bantam with an ACM number around 57,000. It is a number stamped by the manufacturer of the tub and not the trailer serial number. The only 'serial number' on MBT (Willys) and T-3 (Bantam) trailers is on the original data plate. Robert Bills, Apr 20, 2009.

All 3 Military Trailer series share the following characteristics.
  • 4 reflectors.
  • Outboard fenders.
  • 'A' Frame draw bar.
  • Heavy Duty Leafsprings.
  • NDT/NDCC Military Tires.
  • Heavy Duty Shock Absorbers.
  • Same Wheel Rims as Jeep of the era.
  • Open top, metal box body construction.
  • Raised ribbing on floor pan of trailer body.
  • 2 Safety Chains for attaching to Jeep eyebolts.
  • Both Service Running lights and Black Out lights.
  • Drain plugs in floor to let the water out or hold it in.
  • A parking brake makes sure it stays where you left it.
  • Solid Axle, full floating bearings, brake drums andshoes.
  • The Lunette Eye Loop designed for a pintle hook on a jeep.
  • A solid rear panel, not a tailgate, as this would not be watertight.
  • Landing legs so you can unhook and drive away leaving it standing there.
  • Inter-vehicle electrical connection cable of heavy gage attached to trailer.
  • 10 cargo/rope tie downs for tarp cover. 4 on each long side, 1 on eachend.
  • All 3 military jeep box trailers are watertight. They will floatwith up to 500lbs of gear, or the opposite; they can haul water (poorly).
  • The lunette assembly has a strong spring on it that negates the slammingand stress when starting from a dead stop or on fast acceleration.
  • The trailer lunette eye spins in its socket, allowing the pulling vehicleand trailer to be leaning in completely opposite directions. It even allowsthe trailer to flip over without causing the pulling vehicle to flip withit.
Differences between the 3 military jeep trailer models include:
  • Fenders:
    • WWII MBT and 1950's M-100have round fenders.
      The M-416 has squared fenders.
  • Landing Legs:
    • MBT landing leg has 3 positions (3 holes). There was a 1/2 way up positionfor deep mud use to help support weight of trailer in deep mud conditions.
      M100 and M416 only had 2 positions for landing leg - up or down.
  • Floor Drains:
    • MBT has one floor drain.
      M-100 and M416 have 2 floor drains.
  • Grab Handles:
    • MBT / T3 trailers do not have any grab handles.
      M-100and M-416 trailers have 4 grab handles. One on each corner.
  • Parking Brake Handle:
    • MBT has a hand brake with a thumb button on the very top for the thumbto depress to release the cam lock.
      M100 and M-416 trailers have a handgrip handle with the handgrip releasingthe cam lock.
  • Shock Absorber attachment method used:
    • Bantam T-3 trailers used a threaded stud and a nut to hold on shocks.
      Willys MBT used a washer and cotter pin through a smooth stud to holdon shocks.
  • Receivers:
    • MBT - 3/4 of cast socket hole section is above main part of cast bracket.
      M100 - 1/2 of cast socket hole section is above main part of cast bracket.
      M416 - has 2 cast socket holes in main part of cast bracket.

      MBT and M100 cast brackets fit the same in the frame.
      MBT and M416 lunette eyes are interchangeable.

  • Lunettes:
    • MBT Lunette eyes were thinner diameter.
      M416 Lunette eyes are very thick diameter.

      MBT and M416 lunettes and the sockets they fit into were cut at thesame angle or bevel.
      M100 lunettes and sockets were cut at a different angle. They don'tmate to the M416/MBT ones, even though they look so similar to them

      I swap M416 & MBT lunettes back and forth between my MBT's, butnone of the NOS lunettes I had fit in the NOS M100 receivers.

Here is a photographof a WWII Jeep and Jeep Trailer.
Here is a photographof a Korean War M-100 Jeep Trailer.
Bantam trailer serial numbersHere is a photographof a Vietnam War M-416 Jeep Trailer.

M416's are the easiest to find. They are also the newestand in the best shape usually. Here is another Photoof a M-416B-1 Trailer - Side View. Notice the gas can racks on thesides. This is the M416B1 model.
The WWII is the next most common (even so, it is still rare), but itcan cost a lot more because there is more demand.
The least in demand, and slightly harder to find M100 is my 1st choicefor the average person with a civilian jeep. If you are just lookingfor a great looking, great off road, great on-road trailer to haul a motorcycleor lawnmower then please leave the pristine antique trailers to the collectors.Hauling a motorcycle would require cutting a tailgate (losing the water-tightness).Hopefully you will find a civilian trailer or one that is already cut,and not ruin an intact army trailer by cutting it.

Expect to pay between $465 and $900 for either a M100 or M416 trailer.The Willys MB-T & T-3 Bantam Trailers can go for more money. It dependson the condition, and the part of the country you are located in. And rememberit is Willys, not Willy, Willis, Wilys, or Willies. Bantam, not Bantem,Bantum, or even Batman. :-)

WWII Military Jeep Trailers - The Willys MB-T & The BantamT-3 Trailers ~ History, and model differences
Willys and Bantam (and a few others) made nearly identical trailersin World War Two. Officially it is the 'TRAILER, AMPHIBIOUS, CARGO, 1/4-TON,SINGLE-AXLE'. Here is a Photoof Two original WWII Jeep Trailers (Front 3/4 view). These jeep trailerswere used increase the payload hauling capacity of the jeep. The jeep trailerscould haul food, ammo, fuel, people, medical supplies, clothing, bedding,and all sorts of other supplies. It was common to see these trailersin the field overflowing with supplies & equipment as in this photographof a WWII trailer. The Jeep Lube Chart issued late in the warhad the lubrication chart of the Willys MBT/Bantam T-3 Trailer on the reverseside. Photographof Original WWII MBT (MB/GPW Jeep on reverse) Lubrication Chart. Willys-Overlandproduced nearly 60,000 of their Model MBT trailers. American Bantam produced73,569 of their version of the Willys Model MB-T trailers, the Bantam T-3.There are subtle differences between each company’s version. The some ofthe trailer design differences are listed below.

  • Shock Absorber & Shock Mounts:

  • Willys MBT: Willys used a Flat Washerand Cotter Pin to hold their trailer's shock absorbers (Monroe shockabsorbers) onto the SMOOTH stud of the Shock Absorber Mounting Brackets(the same as on their MB Jeeps).
    Bantam T-3: Bantam used a Flat Washer and Nut to hold theirtrailer's shock absorbers (Gabriel shock absorbers) onto the THREADED studof the Shock Absorber Mounting Brackets.
  • Axles: 3 types: 1) with a cast housing in the center (Willys early),2) with a center seam (Willys late), or 3) Solid (Bantam):

  • Willys MBT: Early World War II Willysbuilt jeep trailers were the only ones to come with a 2 piece axle (actually3 pieces, 2 tubes joined in the center by a heavy cast coupler). Willyslater went to a single piece axle with a welded seem in the middle of thetube.
    Bantam T-3: Bantam always used a one piece axle (A design that Willysshortly switched to as well); solid tube (no seam), spot (button) weldedto hubs.
  • Data Plate Stampings:

  • Willys MBT: Willys only stamped the Month - Year of deliveryon their trailer's data plates.
    Bantam T-3: Bantam stamped the Month - DAY- Year of delivery on their trailer's data plates. Bantam's DASH Markwas a numeral'1' stamp turned sideways. If you are lucky enough to have your JeepTrailers Data Plates with a Day stamp, you can use the Jeep& Trailer Day of Date of Delivery Calculator to determine whatday of the week your Trailer was made on.
  • Frame Serial Number Plate:

  • Willys MBT: The plate on the underside of the left front spring hangerbracket on frame does not have a 'B' stamped into the metal underthe serial Number.
    Bantam T-3: The plate on the underside of the left front spring hangerbracket on frame doeshave a 'B' stamped into the metal under the serial Number.
  • Cross Members:

  • Willys MBT: Willys used 4 frame cross members.
    Bantam T-3: Bantam used 3 frame cross members.
  • Tail Light Manufacturer:

  • Willys MBT: Willys used Tail Lights madeby Corcoran Brown (C-B) Corp.
    Bantam T-3: Bantam used Tail Lights made by ARROW Corp.
1/4 ton Bantam and Willys trailers (MBT / T-3) used the same type of blackout lights as the WWII Jeep. However, switching between normal and blackoutlights on the jeep pulling the trailer did not affect the statusof the lights that were running on the trailer. The trailer had itsown light switch mounted to the front passenger side box frame. Here isa photoshowing the small WWII MBT Jeep Trailer B/O Light Switch mounted in thefront of the lower passenger side. There was a small disc (door) thatswiveled out of the way to reveal a small set screw that can be turnedusing the butt end of the Jeep H-700 Key to switch between running lightsand B/O lites.

These trailers were also amphibious! They were designed that way. Thetrailers could be floated across streams by themselves (without a jeepor other vehicle) either by having soldiers wading alongside them or byusing ropes from both shores tied to the trailer. The trailers were designedto also be towed behind 2 amphibious vehicles - the Studebaker Weasel,and theamphibiousjeep - the Ford GPA - both in and out of the water! Hereis a photo of the Ford GPA towing a WWII Jeep trailer full of GI's in deepwater. Another photographshowing a Ford GPA towing and swimming with a Willys MBT 1/4 ton Trailerwhile the trailer undergoes floating tests from 6/15/1942. Notice thedate. It proves that water operations were intended from very early on.

Where do I find my WW2 Jeep Trailer's Serial Numbers?
The Willys MBT and Bantam T3 Trailer serial numbers are usually difficultto locate. MBT's and BT-3's had trailer (vehicle) Serial Numbers stampedin 2 places.

Locating Serial Numbers on Second World War Willys MBT and BantamT-3 Trailers

  1. THE DATA PLATES ON THE FRONT BODY PANEL

  2. The data plates is found on the front panel of the trailer, facingthe outside. It is on the drivers side close to the outside top. It is held in place by 4 screws or 4 rivets. The data plates are oftenmissing. The Nomenclature plate has the vehicle identification informationincluding;the Manufacturer (Willys, Bantam or other Co), the Model (MBT or T-3),the Serial Number, and the Date of Delivery (Date of Manufacture). Thisis the actual trailer manufacturer serial number. These Data Plates weremade out of Brass, Pot Metal, Steel, and Aluminum. Be very careful removingpaint or straightening dents on your data plates because valuable informationabout your Jeep Trailer can easily be destroyed in the process. There were4 versions of the text on the Trailer Data Plates. Two each for Willysand Ford. Two each Early QMC, 2 each Late ORD.

  1. THE FRAME

  2. The frames for trailers were also sometimes stamped. One source ofof stampings are from ACM, the manufacturer of the body tub/frame unitthat all the companies built their trailers on. Another souce for someof these stampings are from rebuilders. Typically there are 3 places tolook on your trailer frame. See pic below to help you in locatingthe areas to look in.

    Location #1 & #2 may have the rebuild serial numbers stampedinto the outside face of the frame in approximately 3/8' high numbers.Location #1 & #2 are not factory locations for stamping the serialnumbers. It appears that the military stamped the numbers there onsome trailers to make it easier to determine the serial number. Manytrailers that went to the PTO (Pacific Theater: Japan, Korea, Guam, Philippines)came back with numbers stamped in the alternate locations. These couldhave been stamped during the Korean War, or Vietnam War or ?

    Location #3 is UNDER the trailer. This is the ACM serial number. TheACM serial number was stamped directly into the frame or support bracket.Bantam trailer ACM serial #'s start with a 'B'. You will have to crawlunder the trailer, lay on your back, and look up at a triangular pieceof metal bracing the frame. This brace is about 5' x 6', and the ACM serialnumbers are stamped into it. The number is stamped under the left frontspring hanger bracket on the frame.

    Serial numbers located in #1 & #2 should match data plate serialnumber on the body. The serial number in position #3, is the Tub Mfg.'s(ACM) number, and not the Trailer Serial Number. The numbers are closelycorrelated. Closely, but not exactly matched. Mr. C. Lutz is keeping adatabase on the relationship of these two serial numbers.

    When I go looking for serial #s, I use a propane torch and a small wirebrush (toothbrush size). These items are the best I know of to help inlocating the Trailer frame stamped serial numbers because there is usuallysome grease, rust, dirt, and old paint to deal with. Hit the area withthe torch until the paint bubbles. Then scrub with the brush. WARNING:The hot melted paint will fall all over you, so wear old clothes and eyeprotection!! Re-apply the heatand scrub till you get to bright shiny metal, and hopefully a serial number.Sometimes the numbers are very faint, in fact, the whole stamping can bevery light, so some care and good lighting will be required to uncoverit.

    Hereis photograph on where to look for military trailer stamped VIN #/ serialnumbers. They could be stamped in any of the 3 locations, or none ofthem.


Post War Civilian Bantam T-3C 1/4 ton Jeep Trailers

After the war, Bantam struggled along for a few years manufacturing 1/4tonJeep trailers (T3C) for the civilian market. This kept the company alive,but only barely. In the end it wasn't enough and Bantam finally went outof business after just a few more years of trailer production. Bantam'scivilian T-3-C trailers were stripped down copies of the Military MBT/T3Trailer without all the features that the military trailers (T3) came with.Bantam went on to produce this basic trailer after the war for the civilianmarket from 1946 until 1953.
Although they weren't a completely new design,the trailers were given the new model name: BT3C. (They are also calledBTC, B-T3C, BT-3C, BT3-C, T3C, T-3C, T3-C by others. A long list to describethe same trailer). Bantam also added some features that civilians wouldfind useful, ones that the military would have objected to. They addedstake pockets to the T3-C, so you could put wooden stake sides (to haulmore cargo) and/or wooden top bows (to hold a tarp up) on the trailer.They discontinued the parking brake assembly. No brake drums on axles,and no hand brake ass'y. The lunette eye style receiver was replaced witha civilian type ball hitch receiver. The data plate size was reduced insize to 1'x3' for most of the civilian trailers, although some early onesdid come with full size 3'x3' plates. The data plates were mounted in thesame place as the military trailers - towards the top of the front panelon the drivers side. These smaller data plates were only held on by 2 rivetsinstead of 4 rivets. Originally these smaller plates were closer to thetop of the top rail tubing, but they were eventually lowed a few inchesmore down the panel. Civilian trailers came with fewer rope hooks / cargotie downs (for securing a cover tarp, or tying down the load it was carrying).Military trailers have 4 per long side, the civilian T3-C trailer onlyhas 3 per side. Both Military & Civilian trailers had 1 hook tie downon the front & rear panels. A dropping tailgate was added and the rearsection had reinforcement gusset panels added to support the body &tailgate. The tailgate was not wanted on military trailers because militarytrailers could float. A tailgate would not allow amphibious use of thetrailer by the Army, Navy, and Marines. It would, however, add a lot moreusefulness to the civilian customer by making it easier to load & unloadthings for the trailer. The gusset panels were needed to compensate forthe cargo body's loss of strength when the tailgate was added to the trailerto prevent flexing and too much stress being put on the body panels andwelds. These panels were the new location for mounting the rear reflectorsand taillights. If the new T-3C came with tail lights, they came with civiliantaillights instead of military black out lights. The front panels of trailerswith no taillights would have been issued without the extra upside downrope hook to hold the vehicle electrical cable when not in use - no taillights,no need for electrical inter vehicular cable, no electrical cable, no needfor a hook for it. The side red reflectors of WWII were discontinued aswell, and the rear red reflectors were moved from the rear body panel tothe outside tailgate reinforcement gusset plate panels. The major changesmade to the BT3 for conversions to the BT3-C in the civilian market aredetailed below.

How to tell if you have a Bantam Civilian trailer.

  1. Look for 'stake pockets' inside the trailer on the long sides of the cargobody wall to allow mounting the cargo body top bows.
  2. Look for 3 rope hooks / cargo tie downs on the side of the cargo body.(Military Trailers have 4 hooks / tiedowns.)
  3. Look for only 2 rivets or rivet holes where the data plate would mounton the outside front body panel, drivers side, towards top. Keep in mindthat some early trailers did come with the 4 rivet 3' x 3' data ID plates.Most civilian trailers had the 1' x 3' data plate.
  4. Look for a lack of parking brake, brake drums, and brake cable assembly.
  5. Look for a lack of side reflectors on the rear side 1/4 panels.
  6. Look for a Factory drop down tailgate & side gusset support plate panelsat the rear panel. (NOTE - Many military trailers have had tailgates hackedinto them. Most were done very poorly). This meant they were no longerwater tight.
  7. Look for a Factory civilian ball hitch receiver. Hitch is a Fulton Standard1 7/8' Ball type. (NOTE - Many military trailers have had civilian ballhitch receivers hacked/welded onto them. Most were done very poorly).
  8. Look for a smaller civilian style electrical connector plug and trailercable. (NOTE - Many military trailers have had their original Heavy Dutycables & Plugs removed and replaced with after market civilian ones.Most were done very poorly).

In 1946 Bantam trailers were available from the factory in Butler, PAin Red and Green paint colors only. The suggested retail price in November1946 was $169.50 plus $8.12 tax for the basic cargo trailer. The UtilityChassis (no cargo body, wiring or fenders) was $126 plus $6.62 tax. SideRacks, Bows and Tarpaulin Set was $35 plus $1 tax. A flat tarpaulin was$12 plus $.38 tax. All prices were F.O.B. .

Other Countries Copy the American 1/4 ton Jeep Trailer.
The World War II Trailers were also copied by several foreign countiesduring the cold war era. There are some subtle and some not so subtle differencesin these foreign manufactured jeep trailers. Differences such as lighting,brakes, and in the number of reinforcing ribs pressed into the floor andside panels of the trailers. Japan, and Switzerland both made copies. TheDutch and French Armies each had their copies as well. WOF (Willys of France)made some of them, as well as GENEVA, MILLION-GUIET, and HOTCHKISS. Manyof these French 1/4ton Jeep trailers had front mounted spare tires (asseenhere and hereand here and here)and are still the companion of the PEUGEOT P4 today. Canada has made acopy the M416 trailer, called the M101CDN, and has really beefed it up and added some really nice featuresas well.

K38 / K-38 Linesman Trailer
TheK38 Linesman Trailer, also called the Telephone Cable Splicer 1/4 ton,Single Axle Trailer for Equipment TE-56, was used by both the civiliantelephone companies and the military in daily service before, during, andafter World War Two. The trailer in Military use was called the G529K-38 ¼-Ton Trailer. The K-38 was a very small covered box trailerthat was used in the military prior to WWII until about the end of the1950's. It was utilized most by the US Army Signal Corps, and by similarunits in the AAC / AAF, USMC and USN.

It is basically an OffRoad Tool Chest on Wheels. It has a liftopen metal top, and a lower pop open cubby hole at the rear. It used16'tall motorcycle tires, had heavy-duty leaf springs, and a lunetteeye and two loop pulling handles on the front of the drawbar. Taillight,foldinglanding leg, and padlockhasp to protect the contents were all standard issue, as was a rearwork shelf. When you flipup the lid (passenger's side opens, hinge is on driver'sside), the insideis full of tray compartments for tooland equipment storage. The 'Military Telephone man' would draw a jeep& K38 trailer from the motor pool and go out for as long as necessaryto run communication lines between units. These trailers were made in farsmaller quantity than regular jeep box trailers, and these trailers seldomcome up for sale. Data plates were mounted on the front body panel in thelower driver's side corner. They were made by at least 4 companies overthe years;

  1. FWD Auto Co.,Eagle Division, Appleton, Wisconsin (data plate).

There are at least 2 M-416 trailers that have been modified into a powerdriven trailer. I do not know of a single instance when the military mighthave done this. Take a M151 rear axle and add it to a M416 trailer. Thedriveshaft runs from the jeep to the trailer, and the trailer's wheelsbecome drive wheels, giving you 6 wheel drive with one point of articulation.The Vietnam war era Jeeps, the M151 series jeeps, have a unique differentialpumpkin with a yoke on both sides of the case housing. This allowsa second driveshaft (PTO) to come out of the rear of the jeep's differentialand extend to a pivot point where the trailer meets the jeep at the pintlehook. Another driveshaft continues from the pivot back to the trailer's(M151) differential yoke.

I have heard of one guy in the late 1980's who added the differentialto his trailer, added a permanent articulating driveshaft, and drove aroundin 6 wheel drive. Eventually he got pulled over for running the jeeps licenseplate on the back of the trailer and not registering the trailer. He wentto court saying it was now all ONE vehicle and therefore only needed oneregistration. The Judge agreed based on the driveshaft power drivingthe trailer. It made the news, but I never heard anymore about it.

M716 / M762 Small Generator Trailer
These flatbed trailers are based on the M416 chassis, and are ratedat 3/4-ton gross. The TRAILER, FLATBED, M-762, have the same shape flatfenders as the M416's have, but these fenders also have the interior (orback side) closed off to prevent water from splashing onto the load. Thesepanels are also needed to support the fenders since there is no body tomount them to the side of.

Re: Dents in a trailer bodies floor
Recently a US Army soldier stationed in Alaska wrote me abouta rough M100 trailer he had just purchased. The floor - as so manyare - was caved in and dented. So I emailed back a old school tipthat I was told about 20 years ago. Thought I might as well postit here as well.
Locate a 6x6, 8x8, 12x12, etc. piece of wood. Cutit the exact height as the distance between the top of the rolled edgeof the trailer and the floor of the trailer (or where floor should be).Flip trailer tub upside down over the standing up piece of wood (you mighthave to add side legs or flat base to wood to keep it standing). Keep repositioning the tub dents over the wood and hammer the dents fromthe top. Re: hammering - With propane torch heat the edges of thedent, then hit with hammer. After doing this a few times you havestretched already stretched metal. So now heat the dent in the middleand after getting it nice & hot toss a cold wet rag on it. Thisshrinks the metal back. Repeat until dent is gone or greatly reduced.Move on to next dent.
Re: Backing up a trailerThe Bantam T3-C Page
I have heard some people say 'the trailer was of very limited use,because you just could not back it up more than 10 feet before it jackknifed. And it was impossible to predict which direction if you started by backingstraight.'
That is absolutely not true. I can back any of my 5 militaryjeep trailers, loaded or empty, straight backwards at a fast rate withno trouble at all. I have had doubting Thomas's before, and haveon several times hit over 20 mph in reverse (clocked by a following vehicle).
Yes, there is a 'trick', that was taught to me by an old motor poolSgt.Bantam Trailer Serial Number
The 'trick' doesn't make sense, and I was a 'doubting Thomas' myself...until I saw it with my own eyes. Then I did try it, and dang'ed ifit didn't work.
No the trick is not 'Steer from the bottom of the steering wheel inthe direction you want the single trailer to go.' (If you really have ahard time or it's your first time backing up a trailer, then you mightwant to try the 'hands at the bottom of the steering wheel' trick untilyou become more proficient at the maneuver).Bantam trailer serial numbers
Although I have heard that this helps people who have a hard time conceptualizinghow to position trailers... It has nothing to do with the trick I am aboutto go into.

Ok here’s the trick. Use it in moderation. Jeeps, Trailers, horses,airplanes and lots of other things can be dangerous to operate. Caveatemptor, and I take no responsibility if you crash, get cancer, or are attackedby terrorists, or anything else bad happens to you.

When backing up, rock the steering wheel back and forth from left toright. There is a certain cadence that you will get the hang of. You want to turn the wheel enough so the truck/jeep just starts to rockslightly - the same way you would rock the car going forward when you wereyoung and driving was fun LOL.

The gist of it is that the trailer lines up (but doesn't turn) to goto the left, and then it gets pressured to re-line up to go to the right,just in time for it to be pressured into getting realigned for a left turn... and so on and so on. This constant 'left push, rightpush, left push, etc.' keeps it straight online.
