Finally got everyone out for the first full camp in the camper. It’s usually just been me, or me and the boys. Finally my wife had time to join us. There was definitely a learning curve for comfort. First night the eldest and I slept up top with one 28” panel removed. That seemed ok, but the next night the kids wanted to sleep downstairs. So tried the same set up, but my wife didn’t like the firmer side of the mattresses (That side only has a 1” topper on the stock, when the other big panel has a 2” topper with the super firm stock one removed.)
So finally the solution is a fully closed top section with the kinds below. BOYO! You can just faintly hear them down there. So will definitely be looking at some of the mods to make communication easier.
The big thing was I got the heater piped to both the lower and upper section. But I just need to find someone to 3D print a vent that will fit in the zipper like this one:
This was our heater setup
