Not too much to update, too busy working to accomplish much, but we have managed to spend a couple more weekends in it. I haven't posted many interior shots because, well, it's not done yet, but here's what I have done to date.
Installed a NORCOLD 60qt fridge in a temporary spot until we get our front counter/cabinets installed.
Picked up some closeout 12x36" cabinets from lowes for some storage above the bed.
We were upgrading one of our beds in the house so the old full size mattress replaced the air mattress in the back. Still a temp solution but works for now until I get a fold-up bed designed. Also has lots of room for storage underneath and is perfect for a pair of roughneck tote bins side by side.
