I'm a solo female RVer. I had a Class B for 4 years and, like you, decided it was too small to live in. I found a 1992 Born Free 26 ft rear side bed model on a lot in
Now I have a living room, and a bedroom. Also the bathroom is big enough to change clothes in. There is a lot of storage, 2 closets and a mini pantry. It is such excellent build quality, I don't care that it is 20 years old. The PO had ALL service records for it.
The first trip was 1200 miles to Montana. Very easy to drive. 10 mpg at 65 mph through the mountains. Not great mpg, but for the $80,000. or so I saved buying used, I can buy about 15 years worth of fuel and maintenance. Ford 460 motor, plenty of power. I will rig it to carry my motorcycle.
