This set up was in the Mattole river campgrounds the night before I left on my Lost Coast hike.The couple had just bought it from Tepui Tents of Santa Cruz, California. I used a tent like this for about 10 years in Baja California and it was great.No need to scramble into the back of a pick up truck to sleep. It folds up into a compact, fairly aerodynamic shape on the roof and in the desert, you don’t have to worry about snakes or scorpions.The ladder acts as a cantilevered support for the foldout section, and the mattress and bedding and pillow are inside so that after unfolding it, you just climb in and go to sleep.
I had it mounted on a 4 x 4 Toyota Tacoma and would 4-wheel it to an isolated beach (where there was surf), and face the screened opening towards the ocean.
The different models run from about $1,000 to $2500.
