Any reviews on PJ Trailers? I'm considering buying one, however I have a little concern over the fact the rails (& vertical members) are bolted rather than welded to the frame (http://pjtrailers.com/detail.cfm?ID=U7). Anybody have any experience or any thoughts on this design? It may be nice to have the option of removing the rails if a load is wider the 72". On the other hand, I want a strong, solid rail which which doesn't rattle or move while under way. If I purchase this trailer, I would like to build some quality sides (approximately 2' above the top rail). Any pictures of similar trailers with wood sides would be much appreciated. I'm particularly interested in utilizing the stake pockets. In advance, thank you.
