If I were to design a pop-up for my specific needs and wants from the ground up, I would make the interior modular and user configurable. You don't see wood cabinets and marble countertops in the space shuttle or the ISS for a reason, it is a professional living and work space. These campers are used for recreation by most people but for some of us, they are for professional use in the field as in my case.
If I could re-arrange and swap out components on the fly and access nearly everything in the camper with a lot more ease, that would be incredible for what I use my current set up for. It could still have some comfortable appointments and accents, but be far more functional than they are now with a minimum of engineering.
It is partly modular and there is NO wood!! Period..
There is also no marble in any of my products... Kinda heavy..
Also no staples...
As DD said, you need a heater...
