Here is a restored old Vintage Shasta trailer for sale. It’s a canned ham style in a baby doll blue color. The camper is a long Birchwood Beauty with new upholstery, wiring, and several other interior and exterior features.
Don't even bother asking the snobs at your local RV place for help with your vintage camper. They don't know anything but certainly these guys do and they have almost everything you need for your vintage camper.
