We loved this trailer all the way up to the coast of Oregon and back.
It's a 13ft Minit trailer made in Pennsylvania in 1974. I've never seen another of this brand, and it had a 3 digit VIN number, so they're production must have been less than 1K a year. When I tried to register in Nevada, they could find no info on this manafacture, so it has been re-registered as a "homemade" trailer.
Its been much loved, and ready for its next adventure.
