    Flexing at top of pinbox

    Has anyone had flexing at the top of the pinbox that you can see when you hit a good bump? Had a screw pull out and punch through the bottom of the front cap right at the corner underneath the clearance light. I know there is going to be some flex, and as this is a 2014 369RL, kinda expect it. I have a washer and dryer up there as well. It is right at the corners of the frame, both sides, so entire thing is moving. How much movement would you expect?

    So are you asking at the wingset or the extents of the deck? The frames have a fair flex to them, much more so in 2014. However, pulling screws suggests a little too much. I would personally have it inspected. It easy to take down the skin on the overhang and front storage to get a good look at the framing and, more importantly, the welds. Some of the corrosion I've seen from coastal summers is unreal, but more commonly the low-skill welds crack with fatigue.
