A lot of the trailer assembly isn't real critical. The squaring up can be done by measuring diagonally from corner to corner (must be equal).. my trailer wound up with a bit of a twist in it (if you sighted from front to back, it was off a bit). But, I put it on jack stands and got it straight when building the tear. Once the tear was built, the box will keep the trailer straight.
Even the trailer can be squared when the floor is put on. Lay a sheet of plywood on it and you'll soon find out if it is square or not... I welded all the xmembers (top only), so it had to be square to start with.
