Hi all! I'm a college student thinking about buying a less expensive RV to hook up to my pickup rather than trying to get an apartment for the upcoming academic year. I'm worried about things like ruining the engine of my truck and getting crummy mileage on the way up to school, though. Also, size of the RV- I'm thinking 15 to 21 feet or so. Any suggestions? Any RV I could afford would have to be under $10,000 and would need to have a fridge, be clean, and preferably have a reasonable shower and a microwave. Also, I'm in Florida, so good AC is a must. Any suggestions?
