For those of you you take your rigs off road you know how dangerous this could be especially if the motor was to die. Compression braking would be lost as well as your brake assist. I feel that this is totally unacceptable for a vehicle that was designed to be used off road.

Wouldn't you get the same thing driving down the highway when you let off the gas going down a hill
