At the bottom of this FleaBay Ad is Trailer shopping 101... I just quickly read through it --- and while it's also some of this dealers sales points ---- it does have some interesting THOUGHTS that a guy should keep in mind... points such as looking UNDER a trailer to see the frame and how much RUST is under it.... and the plywood used etc. So linking here just because.
