Brian Campbell has indeed perfected the art of making a bike trailer home as seen here his DIY Bike Trailer Home for sale with fabricated insulation for the most awesome rest virtually anywhere his bike goes.
Brian has perfected the fabrication of an all-weather enclosure that is light, insulated, very stable, and road worthy. This model is 8′ x 4′ and weighs only 80 pounds. It has a spacious interior that fits a sleeping adult (or two?), has many interior shelves, and is priced to sell (he’s asking $1,950 but says he’ll take offers). He can modify the hitch custom for any bicycle.
Certainly this will inspire others to create some more all-weather bike trailer home for those long trips without breaking your bank on hotel stays.
