This is a tardy post, but I'm sticking it in chronologically -- it is very important. The photo below shows the anchor bolts we used for tying in the studs (wall framing) to the trailer frame. Trailer and subfloor system can and will vary, so the solution for this trailer is quite different than from trailer #1.
We figured the system together, but Amy took charge of getting everything solid, tight, and beyond sturdy.
