turn my dinette into a couch
I would like to turn my dinette into a couch in a 189FBR. I will do this by turning both dinette seats 90 degrees. My assumption is once detached, the 2 dinette seats are free standing. My question is how do I know where to screw into the walls and floor to reattach the benches. I know that there is no electrical and no plumbing in the area so can I screw anywhere I want? This looks like a somewhat simple modification but would like some input from all the experience out there. What should I look out for and what should I prepare for.
