I have a 2015 Salem hemisphere 282RK. They warped and FR replaced them under warranty.
My cargo doors were fine until we had some severe cold here in SC. I can't say the cold had anything to do with it but I noticed it after the cold snap.
Even now the new larger door for the outside kitchen doesn't fit perfect like the OG did but it's better.
They're not made of much and I'm sure they will warp again someday. If they do I'll just try to tweak them.
I agree with some of the posts if it's not leaking don't worry about it. And you're not being picking I completely agree but they all have issues we have to deal with even though we shouldn't.
