I toyed with gluing little round magnets to the rear door panel and then embedding matching round magnets in my HPDE table surface but I figured that the glue wouldn't hold the magnets to the stainless door panel or the glue wouldn't hold the magnets countersunk into the HPDE . The magnets I played with all seemed to be too strong for the application.
Regarding the shape of the table, mine is really just a light work surface, whatever you take that to mean. I use my truck for work so it's a convenient place to set some field instruments, soil samples, notepad, etc. For camping I just wanted a place to set a small pot, small jetboil stove, silverware, lantern, beer, utensils, shades, gun, etc.
I'll posts some pics but for some reason my external hard drive isn't communicating with my laptop's docking station right now. Need to restart but have too many actual work tasks going on the computer right now. Damn work, always getting in the way....
