This formerly unknown trailer now has a name. It is a "Trail Feathers " manufactured originally in California in the late 50s and early 60s. Very similar to, but not a Scotty!

You can see the drop-down floor under the door.
It is operated by the lever seen to the right of the spare tire

The VIN - 60 13 1230
