I'm guessing the OP means that there is twice as much wear per mile as expected.
However, if the vehicle is built to the vehicle maker's body standards, isn't over the weight limits... then I don't see that the vehicle will wear out any faster than a U-Haul truck or other item.
I think the logic is that the U-Haul truck will be empty and so presumably at curb (un laden) at least 50% of the time.
A Class C Motorhome on the other hand is at, or very close to, the GVWR every mile from the day it rolls out the manufacturers door.
