We had a 19' B. Fine for me and the dog on short camping trips but making the couch into a bed that's still not wide enough for my wife and I got to be a pain real fast. Traded up to a 26' class C and unless it's just me again will never go back. Nice having a queen bedroom since our sleeping habits aren't always the same. 26' is still plenty short enough to get into a pull through parking spot with space left over and not so big that we would have to pick our gas stations carefully. Drove several 30+ rigs and they seemed too long and had wasted space and not worth dealing with the extra length and weight.
