The mpg information for Class As is ,unfortunately, correct. Class C do not get much better ,around 8-10 mpg. You can beat this some by getting a Class B but they are expensive ,used ones are rare plus they are a little cramped. Another option is to get a super light weight trailer that you can tow with a small truck or car. <br /><br /> Even with poor gas mileage you can still live pretty comfortably and cheaply if you take advantage of the senior camping discounts. A lot of seniors spend the winter in the corp of engineer parks in the south east- Mississippi , Alabama and Georgia.

It depends on how busy it is at the campground.
