I've seen some rental RV's being driven off-road in places that are hardly fit for an automobile, like the Moki Dugway and The Valley of the Gods unpaved road.
Not saying that all rental units are driven where they should not be but it might be a good idea to closely examine the undercarriage just to see if any damage was done. The rental unit I saw getting drug out of the dirt in Utah might not be a good deal.
As with any RV, an inspection by a qualified mechanic is always a good idea since you have no idea exactly how the coach was used.
