The belly pan is dual purpose, if you wish.
First it helps with a smooth air flow underneath the trailer.
Second, it protects the "under the floor" components, as well as the frame.
It does not offer any structural benefits.
An important note, the underbelly must be able to breathe.
If you replace it, do not seal it at the seams.
Also, use large head pop rivets to reinstall or install the underbelly.
Most underbelly problems come from unbalanced running gear, that makes the underbelly flutter, thereby shearing off rivet heads. The larger rivet heads will offer far more protection.
