I bought mine about a year and a half ago. I did a ton of research and wanted the best I could afford. I did find out the Haulmark is not under the same ownership from days past. It was bought out by a larger corporation and the prior owner now bought Pace. I did buy a Pace. Again, do your homework on the build and the construction and materials used in fabrication and in the Axles. It make s a difference. I wanted floor centers on no less than 16", walls that were the same. The gauge of the outer skin, rivets or bonded sides, torsion or leaf spring, composite or plywood flooring, roof construction, yada yada yada. In the end, new was the only way to go to get what "I" wanted. In fact, it was cheaper in the long run because I didn't have to update and fix someone else's crap. If you're in a bad climate and it sits outside, where will the snow sit (flat roof) & stupid roof vent? Will the floor rot quicker where it's parked?
