Personally, I don't get any of the rolling bed concepts from the teardrop to this TigerMoth type of trailer. There is no way to get comfortable or do anything when the weather is wet, other than sit and wait out a storm. As much as we all like being outdoors, there are always times where you will be cooking or cleaning or washing up. Even reading, whether on electronic devices or checking out a map, it would be nice to have a place away from wind, weather and bright sun to do these kinds of things. For that reason some kind of trailer with the possibility of standing or sitting comfortably at a table is what I would look for. That is the appeal of the Cricket trailer to me. Trailer-like, comfortable standing room. A place to sit at a table with a map or tablet or guidebook, or on your lap and yes, a place to go do your business with a cassette commode, which can be tucked out of the way after use. An 80" length queen bed is a personal thing, depending on your height, yes, and your traveling partner. There seem to be plenty of those sizes with the roof top tents, but for me, those have too many other limitations.
The design seems amenable to frequent design changes so maybe there will be larger ones, but don't expect cheaper. For a mfg, it is all about sales. I suspect he had a number of requests for customized versions, so he's selling the gear model, with nothing but the front cabinet in it. Customize it yourself (my plan). The flurry of late winter, early spring RV shows may tell what sells & the TigerMoth appears to be the only thing in the Taxa pipeline. I'm ready to buy, to do some traveling, camping in 2016. Might be a big year for Taxa... Or not.
