This camper is only 7' wide so it fits a queen bed nice, and there will probably be a little storage available as there is good height in the overhead, I could also go into the main cabinet with an insert which would work good. This unit has a massive amount of storage for it's size, and floor space has a decent flow to it so far. There are also the lower outside storage cabinets on the deck and I have a wall mounted storage locker for the rear outside wall of the camper.
The 3 holes are for Heki skylights, the front one is big enough to legally qualify for an escape hatch. I'm not putting AC or a fan in, we don't have fans or AC in the big truck and it stays nice and cool with windows, skylights, and a breeze, we will see how this one works out, can always add those if needed. There is a thermal dynamic evaluation coming soon!
