Thanks - I was looking at the Zion last night at 2 am
It is a possibility - although those long "benches" (as they seem to call them vs beds) are apparently 25" deep - which is pretty narrow. I have found 28" is about pretty good for comfort. It is true what I read about RV choice is a compromise!
The Crossfit was one I didn't know about - helpful to know there are some options.
Re the RV's with back couches and the two side seats - like the Lexor - don't really work as separate twins - unless I am not understanding something about them. I want space for "non couple" two - and where I do not have to make up a bed everyday(not compromising on that one as it would be an irritant everyday for me). Also, the beauty of full twins is that one can be a couch and one a sleeping area - yet if someone comes along they have their own place to sleep too.
It is very helpful to get info from everyone - thanks!
