I know that all of us are constantly tinkering. It might just be to tighten up a hinge or to find a plug on the TV has come loose.
My point is that anytime we drive our house down the highway it is being shaken apart. Add to that the fact that our houses on wheels have many systems and devices, all of which are relatively complex assemblies and we have a situation in which some TLC is required during or after every trip.
It is easy to imagine that not all owners care to give thier coach that little bit of care, and a lot of things could be left broken and the coach is still more comfortable and has more features that work than the average plastic palace. So maybe the comments in the ebay posting mean just that. They mean the coach has a bunch of little things somebody needs to fix. They could be annoying things like dash lights that are out, or more serious things like a TV that doesn't work.
The ad makes it clear if you buy it, you fix it. This is a true buyer beware purchase, but I still don't see the price as way out of line. It reflects that the owner chose to leave things that are broken unfixed and he is going to have a sales price that is consistent with that. It is also going to be considered by every buyer that if he did not take care of the little things that just need some TLC, he likely ignored routine maintenance.
I would consider that coach to be a shop project. Great for someone who doesn't mind going out to the garage every night and working on the bus for a few hours.
