Couple months ago we drove through a pretty good rainstorm. Afterwards noticed the front closet of our fifth wheel was wet. The left, driver's side, corner. Got on the roof and the sealer looked like maybe it had let some in so I resealed with dicor. While there I pulled the outside upper marker lights from the top of the cap. They were only caulked across the top. Ran bead around wire opening and screw holes. Reinstalled and caulked around the entire light fixture. So far so good. If you have upper marker lights I would have them inspected for a possible entry for water. Good luck...
