I make it a point to chat with RV renters we encounter when out traveling. I've spoken with dozens over the years and not one was ever told about the use of Tow haul. When I explain how it works they are usually dumbfounded. The point being that motorhomes that never use TH slowly but surely cook their transmissions.
Every Class C that has blasted past me out on the highway doing 75+, and there have been a lot of them, has been a rental. Folks that can afford to rent can afford to pay for the gas burned with their foot to the floor. As noted the people who rent could not care less about not abusing their rented coaches. It is a tribute to the relatively bullet proof nature of the venerable Ford V-10 that these rentals survive 100,000+ miles of a base. IMHO a class C, regardless of size, that has a 5.4L V-8 will be hopelessly underpowered. For the record I loved my 5.4 that was in my F-150 SCab but I was only towing a 5,600#, 22' TT.
Given how they are drivien I can only imagine the abuse that takes place with the various internal systems. You may save a few bucks initially when buying a refurbished rental but you will get pretty much what you pay for. Caveat Emptor.
Just sayin...
As always... Opinions and YMMV
