Re: Is this a good price
I agree with Nash - If 11mpg is not an outright lie, it's what they got going downhill with a tail wind!
Check and double check for water damage. Look on the roof and see if there are cracks in the sealant around the top vents, skylights, etc. The A/C units usually have a gasket and is not as much of a problem as the sun exposed caulking.
When water enteres the roof it will usually find its way down the inside of the wall rotting the wood. Open every cabinet and knock and push you finger hard on every inch of the wall. If there is rotted wood many times you will be able to feel it. Look along the side on the outside fiberglass - any buckles (delamination) usually indicates water damage on the inside. Push / knock on the outside too and you may be able to feel any wood rot on the other side. You also want to check under all the windows.
If you find a large portion of weak walls, run away because the unit's structure may be compromised. The last thing you want is to be in an accident or hit an overhang at your house that makes the entire side collapse!
Make sure the plumbing works by filling the fresh water, sewage, and grey water tanks at least a quarter and look for leaks. Don't forget to check the generator, fridge, hot h2o, etc. These items are not deal breakers, however they can be expensive to fix and you would want to take that into consideration when you make an offer.
I once bought a camper that the seller had the fridge ice cold for me when I picked it up. I later found out that it only worked on propane, and would work at all on electric!
Hope this helps,
