Really nice work! I built a "U" dinettes, too, and am still struggling with the single pedestal. The single aluminum pedestal tends to allow the table to lean if someone puts weight on one side. I'm kind of married to the table size and weight since it becomes the platform for a bed. What type of pedestal mount did you use instead of the Marine one?
I am thinking I may have to build a telescoping pedestal to get the kind of rigidity I need and preliminary concepts have shown that to be difficult because of the two heights needed.
