I ended up finding an Itasca Spirit and absolutely adore it.
Within a month of getting it into our driveway, I had done some major interior renovations Pics below. The V6 engine is strong enough to get us WAY up into the Sierras, though we were glad we didn't try it on a day when there was lots of traffic.
The Spirit has the bathroom in the back, which at first I didn't think I liked, but now I think it's the best floorplan for us.
I got a really nice piece of birch plywood (thin) and used it to panel over the ugly plasticy cabinets where it was possible.
I primed the vinyl wall paper, and then painted the walls.
I removed the bulky built in seats and table over the wheel well, then built a little sturdy box to fit over the wheel well. Then we built a light weight tabletop, which rides upright agains the frig, and easily sets up when camped. It gives us LOTS more table room. 2 folding chairs from Ikea work perfectly, and store in the bathroom closet when not in use.
We took down the enormously tacky window treatments (OMG), and are replacing them with roman shades (home made). The carpet/linoleum was awful, so the carpet came out, and we put a teak colored floating vinal floor over the existing linoleum. All in all, with the stuff we removed and the stuff we put in I think we reduced the weight of the camper by about 100 pounds and about 10 pounds of dirt and dust.
The camper now feels VERY roomy, and the over-cab bed, fitted with a memory foam pad is very comfy.
We have had a few leaks, but we caught them right away (it had been parked under cover, and they thought there weren't leaks because it didn't get rained on).
There was one mystery leak somewhere on the right side of the roof, and when we couldn't find it, we just recaulked everything on that side - which took care of that. The front window was horrendously siliconed, we had to remove all of the old stuff and do it right. One of the side windows in the over-cab section also needed a bit of silicone, but I think we are done sealing for now.
This is really a nice camper, and it was well worth the price. Heck, I even like to take my morning coffee out and just sit in it.
