there is alot of good info here. Thanks for everyone who replyed. My first enclosed trailer was a 26 ft Haulmark. I liked it except everything corroded real bad. I then bought a U S Cargo. It was only a 24 and the floor went soft. You could walk across it and feel it sagging. I have been looking at a 34 foot these are $5950.
