Would be great to start seeing some monster jam content in BeamNG. Although i'm not sure BeamNG supports heavy machinery (witch I think would include monster trucks) yet.
Also converting a car from rigs of rods to BeamNG is not easy. Converting maps is a lot easier than vehicles because all you have to do for a map is load the height map in the Torque 3d editor and work on it from there. But a vehicle needs a lot of programming.
There is some info on how to convert vehicles form ROR to BeamNG on the BeamNG wiki.
