I've been kicking the idea around about getting a RV. I weighed the options of mileage between the A,B, and C types. The class b will give the best mileage, but they are the smallest. Diesels get the best mileage but you pay for that luxury. Class A and C get almost the same mileage and can be close in price. So the big question is, where will I store this thing when I'm not using it. And how often will I really use it in a years time, to justify the cost?. If you have acres of land and don't mind seeing it sitting there all the time, I guess that won't matter. They can be pricey but the do look like fun.,,
