One of the first mods in beamng, and one of the best offroaders in the game

Text from the original forum post below......

"The general idea is based on the RoadKill rat rod Jeep and the zero--given-Rx7 that was featured on /Drive. What would happen if the creator of that Rx7 built a custom crawler/baja jeep frame and put a body on it that's dragged straight from the nearest field.
Specs/data:
Engine: Chevy 350 smallblock with a billion miles on it, custom bodged headers and no aircleaner(because why would you...), and animated carburetor 
Transmission: THM350(aka Turbo350) 3-speed automatic(with manual shifter)
Transfercases: Dana300 coupled to an NP241 doubler(so 2 transfer cases combined!), which results in 7 forward gears and 3 reverse gears(because I left out a few gears when they were too similar or not useful enough)
Axles: Dana60s. Eventually the driveshafts will be animated, this will only start working for you guys when the Race update has been released.
Wheels: 37" Irok tires wrapped around widened 16" HMMWV(Humvee/Hummer H1) rims
Body: early 1942 Willys MB. Front fenders are raised and rear wheelarches cut to allow more flex with bigger wheels. Windowframe is chopped for extra gangster-lean.

The black-out lights all work properly(as low beams) and all the body/accessory parts you'd expect to move in real life, move in-game too.


As far as possible, the invidividual pieces of the car all have their real weight(transfercase, axles, fenders, hood etcetera).


Many thanks to anyone who helped "alpha-testing" this, especially Dkutch and Dennis-W. Also thanks to Dennis-W for letting me almost straight-up "copy" his Dana60 axles and re-tuning my suspension. "
