We have a 2003 Class C MinnieWinnie 30' in very good condition. We could sell it for the high $20's, maybe more. Newer Class C's and A's (2016+) are $60K+. We love the MInnie's layout, everything works but it has 65,000 miles on the Ford E450/V10 base. Does anyone think we should sell and move on up to a newer one?
