Last year we traded in our trailer at the time for a slightly used Arctic Fox in inventory at Curtis Trailers in Oregon. They provided a rather complete "starter set" like those that often come with a new unit. I appreciated that since a lot of our hoses and such were getting old. Still, I wanted higher quality stuff, so I asked if they'd give us credit to swap. No problem. In addition we got a significant discount in their parts store at the time and for the next year. It wasn't a big expense to them, but it made a very good impression. I was smiling when we drove off the lot with our "new" rig.
