Wow,
I like this layout... though it must be an older model. I just bought a new 2014 this year, and thoroughly researched a lot of the new models. I went with a TravelStar 239TBS, which is similar, but has the 3rd queen tip out in place of the bunk beds.
The thing I like about this is the bunk beds would make "turtling" a more convenient option, esp with kids. Hmm... seems like a hybrid's hybrid: hard sided TT when you want it, soft sided when you want it.
I'd be inclined to encourage manufacturers to bring back this layout. A little bigger option too though with a slide-out U-dinette and jackknife sofa opposite to it, like my 239TBS has now. Bunk beds probably make it heavier than the HTT market could support. I'm on the upper end now of the HTT weight market at 6,500 max... for that weight you need a strong TV, and might as well look at Bigger TTs or 5'ers. I like canvas though. Open, airy, bright. Fun.
Very interesting, but sorry I'm no help!
