Well we now have a utility closet wall at the rear of the trailer. The center opening, near the top of the wall is for a window. The opening to the upper right is the A/C opening. I designed it large with filler blocks in case the 5000 btu window unit is not big enough, it is large enough for an 8000 btu when the filler blocks are removed. If they change the size of the units we have extra room without tearing up the wall to get it. The studs are 20" apart so large plastic storage boxes will fit between the studs and the bottom 2x4 will hold them from sliding. There will be a 2x4 ledger board at 32" from the floor which is the height of the bed. The bed will extend out 5' from the wall toward the front. A queen size bed is 5' wide.
We next insulated over the interior wheel well. We put insulation over the top, sides and ends then built a 1/2" wood cover to hold the insulation in place. This building of the 2, two sided boxes with the ends took a long time. We did glue and screw it together. We took a lunch break and came back an hour later after gluing the 3/4 x3/4 nail board to the plywood and had it on the wrong side. After pulling the screws I hit it 2 times with a 20 once hammer to knock it loose. It tore loose part of the plywood so I had to make a new end. That gorilla wood glue is amazing. If you look you can see the small board on the floor and the larger one on top of the box. These are there to secure the covers in place. And the top one will allow for a place to screw the finished wall paneling.
