Just picked up our new 2014 303rls. I was cleaning it and noticed that the underbelly corrugation was no sagging, but a little loose in the center. All the edges are still screwed in but it seems like there are not any screws holding the center up to any crossmembers. I can push on the center with my hand and it flops up and down a good 5 to 6 inches. My travel trailer I traded in was a low unit and the underbelly cover was solid. The 303 is brand new and we have not used it yet, so a plumbing leak is not my concern. Can anyone confirm if this is normal in the reflection line?

Thank you in advance!
