I brought this up in RoR almost 2 years ago and it never got looked at, so maybe because BeamNG is still in the early stages it can be implemented. Nearly every off road AWD vehicle is equipped with a so called transfercase, this allows the vehicle to be put from AWD to let's say RWD. Not only that, but transfercases commonly used by crawlers also have the option to be put in a low gear for crawling other then the 1:1 "HI" setting. On my Jeep Wrangler on Rigs Of Rods I used a simple work around to simulate the high and low gears of the transfercase, though it's impossible to switch to FWD/RWD What I would like to see is the ability to manually switch high, neutral and low independent on each axle/differential.
