I've been playing around with sketchup making a whole bunch of the designs around a box of 75"w x 10' long and 5' high.
Here's the latest I've come up with. The black portion of the top would pop-up in the rear. I think it has a general layout that would allow us to step inside and be able to stand up and get changed inside and sleep 4 without having to break down a bed
I haven't figured out where to put storage, water, fridge, batteries, etc but there should be plenty of room underneath the beds and an opportunity to put in more storage along the left wall.
