Trip prep Lug nut torque

[jvbutter01]

hello all,
I come from the auto industry. When installing new rims on a car/truck, we always tell the owner to come back few days later and have us retorque the wheels.

I just got a "RV news tip" email. it was telling the readers to recheck torque each trip you make. Why? do they loosen up more than autos do? i never check my truck or SUV before i drive it
