It seems to me that the real question here is what are the general principles required to flat-tow a vehicle behind an RV.
Surely, if a vehicle had locking/unlocking hubs, and didn't spin the drive shaft(s) it would be flat towable without damaging the drivetrain. But vehicles are flat-towed that don't have unlocking hubs, so there must be a less-strict requirement than that. Jeeps are flat-towed by putting them in RWD and the transfer case in neutral?
Are there other requirements? A steering wheel that can be unlocked for the vehicle to turn and follow the tow vehicle?
A supplemental braking system that activates on the towed vehicle when the towing vehicle brakes? (Although the JDM mini-trucks are around 1500 lbs, so braking may not be required.)
