Question: does it fold for storage ... like the Harbor Freight trailer that looks similar?
Document: This is a great trailer. As advertised. a few of the rails came in with some minor bends on the ends. Easily fixable with a crescent wrench.
This trailer is ok but when I went to put a plywood top over the frame I found the trailer was not square. In order to square up the trailer, I will have to drill new holes as the current holes in the frame are about half a hole width off. This makes a big difference over the 8 foot length. Since I am making a teardrop trailer, I want everything to be right.
Answer: no
