I recently purchased a 1976
Surfside and so have been doing some research into them. I also have a
Boler but knew nothing about the
Surfside. They were offered in two configurations; the one that you have and then the one that I have, which has a two-sided dinette at the back that converts to a bed, the side kitchen, and the gaucho bunk at the front. For your layout, the benches at the back are for a three-sided dinette that then would also make down into a bed. As far as moving the kitchen, I would just be sure you still maintain the floor-to-ceiling structural supports in some way.
