Up grading my Class C

I did the same thing. Sold our well loved no issues that I knew of with some rear body damage that I waterproofed. It was a 2003 Itasca Spirit 22e with 55000 miles. I had used eternabond on all the roof seams and around all the light openings and the tape was still in good shape 10 years later. Our reasoning was getting a larger unit with more sleeping space. We love to take our grandkids and their parents with us. We did find a 2018 former rental with just over 50000 miles in your price range. Bought it in late March listed near us on RV Trader. It’s a 25b and I don’t see any decline in coach quality. Nice hardwood cabinet fronts same stove, toilet quality, a bit nicer faucets than ours had and had replaced. Bigger tv of course and a rear bed with space for another tv. I plan to keep this one at least another decade. Maybe we were just really lucky.
