Buying a Class A or C motorhome for family of 4

Honestly, and I'm saying this to try to help you, a $10K budget for a Class A or C sounds like the beginning of a painful journey. If you're very careful and lucky you might find a good one, but you're looking 20-30 year fold RV's at that price point. Hopefully you've also set aside some money for repair and maintenance because I would certainly expect that. But again you might get lucky and find one in your budget that has been very well taken care of. Good luck!
