Man - this forum is AWESOME!
I just posted my original question TODAY - and already a ton of responses! I am very impressed!
OK - to address a few things -
Here's what I did see when I went to see the camper: no mildew smell, at all. It's been well cared for in that regard.
Secondly, the seal between the bottom and top was replaced when the current owner re-skinned the top half, so I know the seal is tight and in good shape. Saw it myself. It looks good.
The gliders/slides all looked to be in good condition, but I did not reach up under the top half and feel the condition/solidity of the internal components. I'm guessing that they're in relatively good condition.
As far as the roof leaking, it was the current owner who pointed out the teeeeny little section of peeling paint to me. I didn't find it when I first walked through the camper - they showed it to me, so I feel like they're being fairly straightforward about it all. That, and we live in a pretty rural area - so deception doesn't last very long.
Sam, I like your idea of having an RV place check it out - but that's another 35 or 40 miles away. I may be able to convince him to let me drag it over to a dealership for an inspection. I'll see what I can work out with him. One thing we didn't do was check out all the systems; there was no water in the tanks, the A/C wasn't plugged in, the heater wasn't fired up, and the refrigerator wasn't on. Any/all of those items could be malfunctioning and cost some serious loot to replace/repair.
Sam, when you say "recoating", are you referring to applying new caulk to the roof? I can probably swing that. Is the caulk anything special? Is it some sort of bomb-proof weather-resistant stuff? Can I find it at most hardware stores?
Is most of the stuff lining the roof/windows a caulk-like material? Or a more durable rubber? From what I could see, whatever it is, it's starting to peel/crack all along the lining of most windows, and the side/top seam was cracking as well (the caulking was cracking beneath the rain gutter). Can I scrape/pull all that stuff off easily and start new? It's painted now, that's why I thought it might be a rubber of some kind. One of the windows was letting in some water (it was raining while we looked it over), but again, it LOOKED to be an exterior caulking issue. I could be wrong - but that was my initial thinking.
Fireballsocal - you purchased an '03 22' for $5300? I'd say you STOLE that thing! Were you wearing a mask and carrying a handgun?! That's a great deal from what I've seen. Of course, we're shopping at EXACTLY the wrong time for deals - I realize that.
At this point, I'm going to get back in touch with him and see if he won't make me a deal. His price may still be a bit strong, but it will save me from driving 1000 miles to pick up an alternative camper in California. My wife and kids LOVED the camper (especially compared to our existing popup!), and will be thrilled with this one. We could likely use this thing for another 2-4 years and get the lion's share of our money back (assuming we can sell it for $2500 +/-).
You guys are outta sight.
I'll be back with more questions very soon - I know it.
