Hi, Although this is clearly only a concept, many comments on various web sites complain of the lack of roof, of the transparent covering, the lack of plumbing, the inability of the unit to fit in standard camp sites, and so forth, as though the mobile mini-house were a realistic proposal. An example is the writeup on dvice.com that said, "Hope you aren't shy: the shower features a wall that'll barely hide you from other occupants in the house, though expose you to the rest of the world." sandiego relaestate
