Down hill grade
Relatively new to RVing. My question is while driving down a steep grade road the engine will rev high. Should I gear down? And best way to do this while driving? Thanks for any help. Stay Safe......

If a diesel engine in a vehicle has neither a compression nor an exhaust brake nor something similar, you just don't have much engine braking available, and so of necessity must rely on the service brakes for more of the braking. Everything else being equal (same vehicle weights, same service brake setups, etc.), that would mean you'd have to descend at a slower speed overall so that the rate at which the brakes must dissipate energy is kept lower, assuming you're in a situation where you might otherwise run out of braking power.
