Finally got the ceiling insulated and installed the lighter cedar planks (tongue and groove). I used some extra ceiling wood, milled it down, and am trimming out the ceiling line, windows and door. I think it adds a nice touch.
I finished the interior cabinet. I used a piece of the piano hinge I salvaged from the old trailer to make the access door for the fridge. It'll be nice to just open that when we want to get something out of the fridge. Was very happy it cleared my lights.
With the interior about 98% complete, I couldn't resist putting in the mattress. Even though I measured many, many times, I was thrilled that it fit width wise. It's a 6", tri-fold, mattress.
