Looks like a Bethany Pickupper. Made in the 1970's. There are a couple on here people have finished. You can google it for more info. I am working on one right now, I also just finished replacing the roof. I used the rv cell membrane material. All the others I have seen have beds on both sides. Mine has a bed on one side. Good to see another one!

Wilyamo: Got any pictures of the "single wide" Bethany Pickupper. I would like to see a couple pix of the outside and several of the inside. Sounds like a neat unit! Also sounds like what I am looking for as a hunting and fishing trip camper for one or occasionally 2 people.
Also, what is the closed cell foam you used for the top rebuild.
