eddyturn - yep, those are real world - and why there is no one perfect layout for everyone!
I am 5'10" and the curved wall behind the gaucho is okay, albeit just barely. The trim out of the CCV pop top allows for better trim out with its 54" wide bed and ~52" clear width between bed support rails. But, if I were 6ft I would have to slouch a bit or cheat the height of the seat cushion lower which then presents other comfort compromises. A SMB gaucho pop top would be an altogether different experience with the narrowness of the opening in the pop top and how far the bed rail projects inboard over the gaucho.
In consideration of layouts - I have played with "50" layouts having a half removable fold down seat just inboard of the cabinet and split rear cushion platform. Nothing installed below /under the removable seat for long things such as skis, lumber, or a 4x8 sheet of plywood, etc. This setup would accommodate those items rather than having to recline the whole seat back and putting stuff on top of the bed.
In our walkthrough pop top, we have had dinner inside at Mammoth during the winter for six, very comfortably, toasty, and the long counter serving as a prep surface and food buffet. There would be no easy space for a 70lb doggie but I can carry 12ft lumber on the floor inside w the doors closed. As said, the walk through puts the porta potti in the passenger side rear corner which provides privacy and ventilation w the pop out window.
Our "50" layout fixed top has been super comfortable dinner for four, the fold down sofa bed is not quite as comfortable as our pop top bed since also has to be a seat. But parking and hanging out/going to sleep nearly anywhere in stealth is not easy with our pop top. The usable big squarish floor creates a living room feeling with the front seats swiveled around snd would provide stretch out space for a larger doggie, if we had one.
I always ask customers LOTS of questions (some a bit personal really) when they are considering interior layouts / builds. It is usually at least few hours of time and multiple phone calls especially for people who have not had a rig like these. Even people who have had slide ins, travel trailers, etc. have misconceptions of what is possible in a van based rig. Experience spanning a broad range of real world uses, personally and vicariously, is so helpful!!
My definition of a "happy customer" is one I run into at a campground after a year, or one's who send me pictures, and they have had a great time in a layout that works for them!
