Seeking a 5.0, prefer a TA model. Doesn't have to be in perfect condition but there shouldn't be any structural issues. I'd prefer a model set-up for a fill size truck. I can wait until the end of summer if you'd like to squeeze out that last bit of usage before you let it go.
If you'd like to move to a Class C, I've a 2006 Tioga 31S (F450 chassis, V10 gas). It has under 50K on the ODO, a generator with ~100 hours and is in great condition.
