I40 in Arkansas is brutal. We towed our trailer, with new axles, across Arkansas, and the road was so bad the toilet tore loose from its mounts and ended up in the living room.
With that in mind, I'd watch for popped rivets in the interior, hinges working loose, etc, on subsequent trips. Don't look for a problem that isn't there, or that you can do nothing about. I would stay off the bad roads if I ever have to go back through Arkansas again.
Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.
