Well, as the other posters said. Make a list of pros/cons. We had a Class C and LOVED it, we would get a rental car if we wanted to sight see. However, it sucked gas like a sponge, (V-10), Tires, maintenance, insurance, AND payments were really expensive compared to a trailer. Maybe you just went too small, with a 21ft trailer. We have a 26ft trailer, now. It's a really good size for the two of us, as we have a nice bed and bathroom. Pretty easy to tow and park. As I get older, I don't want to make big purchases. Good luck with your decision!
