If the bottom is going to be rigid folding panel i could make the sides top and back rigid folding panels too and not mess with the inflationary stuff??. If i connect a rope and pulleys to the ends of the panels they'll pull together and unfold/extend. How advantageous is it to have 5 of the sides smoothly curved from inflation instead of more flat?(cap has 2 sides too) Of course theres the hybrid version with folding panels inside the base of the tail and an inflatable piece for the tip. That could give me the tailgate storage space if i desire it.
