Hey just so you know, I called my dealer about the patch in my Eagles enclosed under belly. The sales manager informed me it is so the enclosed area could breath so condensation does not build up in there. He told me not to plug it. I was going to get the underbelly tape and repair it. But now hearing everyone has it , now I know it normal. And I don't want condensate in there.
