We are looking for any 13 16ft basic U Haul or Scamp Style trailer. We would be open to a range of trailers from fix it up projects to fully ready to roll. I think our top end price would be about 7k. We would be willing to travel up to 500 miles or so depending on the rig we find. We are located in Seattle.
You will be better off with a Scamp. The Uhauls use many proprietary parts unique to only them. Those parts are long out of production and difficult or impossible to find. Some design flaws in the Uhauls also. Scamps are still in production and many parts are available.
