Apparently so, as Toyota is drumming up big numbers in California. Japanese company Camp-Inn has designed an extension of Prius rear hatch space - in a creative way. At the annual Tokyo Auto Salon (car show), they displayed a new kind of roof camper.The device extends rear capacity, as well as protected roof storage, by 20 inches. With your Prius rear seating folded down, Camp-Inn claims "two can sleep in the top bunk, and with the hybrid's rear seats folded down, another pair can catch 40 winks below."1
Of course, you'll need to supply a Prius of your own, there are many at DARCARS Toyota Silver Spring at 12210 Cherry Hill Rd.. There will also be many strange, yet useful concepts, coming out of Japan at Tokyo's Auto Salon continues.
