Planning on buying a Roadtrek -- Advice?

If a 2003 is in as good condition as those few photos show, I doubt you can get one for $15 to 20K - maybe the low $20's. For your information you should be able to find a 2002 190 Chevy Roadtrek for less because 2002 was the first year that Roadtrek model was introduced and it has the same floor plan as the 2003. I have a Chevy 2002 Pop and the model is extremely well built - no question better built than current Roadtrek models. I travel solo and the Chevy Express handles great, is quiet, extremely comfortable and I am not tired even after driving 11 hours.
