Got the man door cut in on friday.
I built the steps out of .080" sheet metal and fully welded everything. I Framed the door in 2x2 .083" box tube. The first step is hollow and I will put a hatch in it when I get a chance.
The steps are 10" rise 10" run. I am going to run a 28 series kwikee step outside which gives me a 16" step off the ground and 10" steps everywhere else.
When i cut the steps in I realized that the decking had most of the bolts broken we we refastened the floor then went about insulating the floor.
The floor has been padded up with ripped down 2x3's 2' on center. We used low expanding foam to stick 2" ridgid insulation down between the sleepers and glued 1/2" sanded plywood down with PL400 and screwed everything down.
The camper portion will be 8'6" inside with a queen sized bed that sticks into the garage area 5'5" off the floor. This bunk will be removable so I can have a full garage or a full master bedroom.
