Thank you everyone for the input
The windows are single pane, thanks.
I have not test driven it. When we first talked to the salesman, he said to make an appointment for a test drive. I thought there's no way I'm giving them that kind of warning. I want to see how it starts cold. As it turns out, when all the batteries are completely flat it doesn't start at all. (I had a hunch...)
Thanks for offering to make a copy of the manual!
My wife went through all the paperwork. It appears the fridge is the original. I saw a picture of another Residency for sale on the web and it had the same fridge doors.
The tires are older, from 2003 and 2005.
We did look at it again today. We still like the floor plan and the cabinetry but I found a few concerns. Overall, the coach just doesn't look like it was maintained well. It certainly wasn't cleaned well.
We found receipts for tires and a brake master cylinder, but no maintenance records at all. The tranny fluid looked good but the engine oil was quite dirty. I picked all manner of junk off the top of the motor, .22 rounds, peanuts, Barbie Doll accessories...
They obviously cooked with grease and weren't very particular about cleaning. It would take the better part of a day just to get the upholstery cleaned. The carpet is dirty enough it should come out. For some reason, the carpet on the doghouse is different from the rest of the carpet. It's funny all that we didn't notice the first time we looked at it.
All the cabinet doors and drawers worked except for one, but there was water damage inside a cabinet from a prior leak around the water heater. The rear window leaks down both corners. There's water damage inside by the head of the bed and underneath, at the top of the basement. The pull curtains in front had missing rollers as did the hard plastic shower curtain. A handle was broken off the fridge door. The shower head was broken -- little things like that make me think maintenance wasn't a priority for the previous owners.
Brake fluid was leaking from the master cylinder, the metal fittings on the brake lines were significantly corroded -- I'd imagine they're frozen solid. There was deep rust at the front of the coach on and around the engine (a sticker indicated it spent some time in New Jersey). The tires are older, '03 and '05. The exterior was heavily oxidized. Most of the basement locks did not function. There were multiple dings on the bottom of the basement doors that had been painted over with a rattle-can. The roof was in very good condition though -- rock solid.
I'm afraid if we buy it, I'll be buying someone else's problems and we'll end up fixing those problems for a while to come. I should probably mention they want $20k for it. As it sits, I'm fairly confident it's not worth half that. I suppose that's the kind of day a fellow should expect when he closes the door on his Jeep-car and the window falls down... :(
