I have found a few "underbelly build" blog posts where folks have used aluminum panels to span from one frame member across to the other side, using self tapping sheet metal screws into the web of the frame beams.
I am not sure that this would have the strength or rigidity to support foam insulating panels, but it is a simple solution.
What do the "four season" manufacturers use on their underbelly enclosures?
One issue with not making the panels somewhat semi-rigid at least is if you remove one it is hard to match up the screw holes in the panel with those on the frame. You have to basically jack up the panel somewhat flat so things match. With the system I used you just bolt one panel to the other and then lift the sides where the aluminum is and put on the "beam clamp".
