I just looked up slide-in popup campers for small pickups. Here re some pix of $600 self-comtained Palomoino (1990). My A-cat is 66 inches between the hulls, and 9 feet of hulls bow to crossbar: everything fits- back to front on my boat trailer, door in the front- sleeps 2 or 3 as is leaving the overhead part over the boat.
