An electric RV seems like a natural fit; many campers looking to enjoy the outdoors are already mindful of their eco-footprint. But the RV industry in North America has been slow to adapt green technology, and the European electric campers that have come to market have been plagued by limited range. Love campers and trailers?

It makes sense, then, that some enterprising campers would turn to electric vehicles already ubiquitous in American streets. We’ve reported in the past on how people camp in their Tesla Model S using “Camper Mode”—the long-lasting 90 kilowatt hour batteries on the car allows for climate control and air filtration all night long, without any tailpipe emissions or sound. The beds also fold flat, allowing car owners to sleep on blow-up mattresses in the back of the car.

Now, a Slovenia company called Dreamcase is upgrading the blow-up mattress, with the Tesla styling to match. As reported by New Atlas, Dreamcase sells a fold-out bed that can turn a Model S, Model X, or Model 3 into a simple camper. Each sleek case packs a multi-layer memory foam mattress, duvet, pillows, and a four-panel bed that folds into a level sleeping platform.

The Tesla Dreamcases are priced between US$709 and $779 (before shipping or taxes) and are available for the Model 3, five-seat Model S, and five- and seven-seat fold-flat Model X. Dreamcase also makes mattress cases for other vehicle models like the Alfa Romeo Stelvio and Jaguar I-Pace.

The $700 price tag seems a bit steep for a glorified mattress, but we’re betting that at least some Tesla aficionados won’t mind. And it’s certainly a more realistic solution than this rather bizarre Tesla Model S-based motorhome prototype.
