Well that does sound like your problem, like I said before all trim and screws are all part of the structure strengh. I like to do on older units is remove exterior trim, clean old butyl off and replace all the fastners to get the best seal possible and often find many screws loose and/ or rusted away so I go from the original screw of a # 8 to a #10 etc. You would really notice how much stronger and quieter and more leak free you rig would be.
