Overall the thing is really impressive. I look at what SMB is doing (and charging for what they're doing!) and realize that if the Europeans ever get it together to bring their camper vans over here the market is likely to change quite fast and I suspect it won't bode well for SMB. The interiors the Euro's have had for decades are so much better designed, more versatile and better built than anything available here.
Mind you, this is a forum where the worship of the body on frame design, the peak of engineering in 1908, is still venerated as an object of sanctity so maybe SMB will still be able to sell a few of their interior conversions...
