My wife and I are Donna D's Northern California Compact II (1973) connection. We recently purchased our Compact to be used as a loner trailer to friends and family that would love to camp, but don't enjoy tents anymore.
We are in the I-80 foothills above Sacramento, and you are welcome to come/visit/measure almost anytime (I work from a home office). I will likely be removing the trailer body from the frame this spring in order to clean, repair, and paint
I'll PM you with contact info.
