I checked the area and it all seems to be intact. From what I could feel, there is no gap.
I do believe it's the header beam as described, thanks for the info.
I have been talking to Terry Milarczyk@ Forest River and he advised this is not "normal"
and has made arrangements for my unit to be transported to the factory for inspection and repairs!
Terry has been more than accommodating and very helpful with both this issue and my fading cap repair that was just completed!
I was really worried about forest river not taking care of us but Mr.Milarczyk has been awesome and knows great customer service!
Terry has made arrangements to pick our unit up and transport back to the factory to have needed repairs completed. He called it a "good will repair"
Thank you for everyone's input and advice. I will be posting the out come once they inspect it.
Again hats off to Forest River for their outstanding customers service and having a guy like Terry Milarczyk on their team
