Thanks for the tips folks,
That sounds exactly like how I am proceeding. Boy, that reinforced
fiberglass is pretty tough stuff to cut. I'll take some shots as I go. After looking at some of the incredible work people have done to convert bunks my mod will be an example of the easy way out.
It looks as if a couple of dinette mods supported their tables with a single pedestal and large cups mounted on the floor and table underside. I'm hoping a single will work. Otherwise I will probably need some wall attachment. (Trying to avoid more holes)
