I spent the weekend installing my walls and betting them square. I first cut a small hole where the doors go and using a c-clamp as an attachment point used a synch strap to pull the base of the wall together. I then made to temp crossover studs at 63" inches ( the width of the trailer ) at 3 points along the wall and made sure the width was uniform. I then attached another synch strap from the bottom of the starboard wall to the top of the port wall and made sure the wall was square. I then repeated for the other wall. Once I could see that both walls were square I attached a diagonal support from the wall to the block on the floor. As added support, I added to pieces of 67.25" pieces of scrap lumber and places in a X and the bulkhead between the galley and sleeping cabin. I then tied down the walls with 2" screws going through the 1" stud along the floor into the floor section of the trailer as well as along the outside plywood overhang.
Next steps, attach my two center formers over my temp cross studs and glue in my real cross studs along with right angle wood supports to keep the walls square. This is similar to the way I constructed the fuselage my HiMax aircraft.
