I am interested in a trailer posted in the classified section, and don't want to buy anything sight unseen (not into surprises!). How can I find out more about this trailer? It is an 800+ mile drive from here to look at it, and we don't really want to make that (expensive) drive unless we know if the trailer is actually as advertised. And it will be two weeks before we can go, anyway. How can I find someone to inspect it for us, and how does that work? What does it cost? Thanks, NEWBIE here!
