Never..............
If I have to rent it out to make ends meet, I'd sell it.
Rental motorhomes such as Cruise America or El Monte are custom built units just for them. There are no awnings to get ripped off, no retractable steps to jam and get ripped off. Everything is very heavy duty. The curtains (not pull down shades that the strings break on) are very heavy duty too. Everything is made with the thought of what could someone do to destroy this. The Class C units also have (if Ford) a 5.4L V8 rather than the V10 (or the current 7,3L) this is to keep people from running way too fast with them.
Equipment such as dishes and blankets, etc are rented separately, and inventoried when returned. Nothing is left to chance.
Co-worker rented a Sprinter class C for a trip. Griped about how underpowered it was and how he had to drive with it on the floor the whole time to get 75mph out of it. Also griped about having to run the roof A/C continually on the road as they were in Florida, and how many times he had to refill the propane. Very hard on it and typical of the abusers who rent stuff.
