if there is access you could also inject a low expansion foam into the voids to create that stability. I have seen that done before.

I am not opposed to this idea but the space is roughly 4" tall. I am not aware of foam (unless I use 10 cans) that expands that large. For now I cut a collection of pieces of 2x6 and 2x4 and added support in different areas I can reach. Towing it this weekend so I will see how it holds up. Definitely much better than it was but not perfect. I'll see how it goes.
Thanks all!
