Here's one for you guys. These are pics of both , my parts truck and my project. Some of the pics are tough to see but the gist of the problem is that on both trucks, there is bulge where the top of the cab meets the drip rail on the passenger side directly above where the a pillar meets the drip rail.

Our theory is that water builds up and freezes, creating the bulge. Anybody else seen this? And what do you think?
