Some final touch ups with the welder
Hannah cutting lumber for the sub floor
Because of the height of the trailer, we had to build the sub floor down into the frame to give us as much room above the frame for building as we could get. With 13′ 6″ as our max and a planned loft for sleeping, we needed all the inches we could get (the final project came in at 13′ 5″).
The underside is lined with house wrap then insulated with two inches of styrofoam
The finished sub floor with roughed in plumbing
The walls framed up – yes, I did overdo it on the studs. I wanted to make sure it was sturdy enough.
I tied the top plate to the frame through the sub floor at strategic points around the trailer using 5/8″ all-thread to insure that we the walls weren’t going anywhere. Not shown is that I also ran all-thread from side to side on the metal frame rails to ensure the strength there.
Every rafter is tied down with a hurricane strap
And every rafter is reinforced with strapping across the ridge beam
The exterior walls are covered in 5/8″ OSB
Then wrapped in Tyvek-like house wrap. Here you can see the slide-outs for the first time
