Thanks, I've really appreciated all the info from today's responses!
The Sunrader really does look like the best option at this point. I'm of course dreaming of a 4x4 model, but that's a future goal unfortunately, considering my budget. I found a Sunrader in good condition in Oregon for $4500, but the interior was semi-stripped, so it would need some project work. The under-developed crafty side of me had its interest peaked.
With regard to previous owner's care; is it storage with a cover that can help prevent rot, as well as the location of storage, etc? Is there anything else to consider in this regard? I'm assuming that not every owner of an alumnium or all-wood framed camper goes in to investigate the status of the interior construction ...
I will keep looking! I will not be discouraged!
