No. I want to be able to keep them inside and guarded by an alarm system that's appropriate for a $250K vehicle. Anyway, the roof is too damn high for quick access to an outfit - you'd still want vertical tubes on a rack up front.
the company would probably be willing to do some customizing work. I believe their stand production models include things like granite countertops

and luxe cabinetry and toilet/sink fittings. The company's home page shows interiors that look to have come out of Architecture Digest. I'd rather something I can clean easily, with a hose. Cooler space inside, as much for dry as wet storage. A solar roof is fine by me, it need not be incompatible with a kayak or even a tin boat; access is the hard part.
And it would be one hell of a mobile blind for wildlife photography. If I'm going to dream about the Earthroamer, I might as well fantasize about Canon's 800 mm. telephoto at $125K too.
