Caulking Around Windows

I was checking out the caulking/seals around doors, windows, lights, etc. on all 4 sides of the rv. I'll check the roof tomorrow.

I found the sealing material that goes between the windows and the exterior wall is starting to crack, above several windows.

I'm planning to use a small bead of silicon caulking to reseal. The silicon around other exterior parts is holding up very well.

My trailer is about 3 1/2 years old and is parked under a rv port. The back end is open to the elements and sunshine.

Posting this to remind everyone to check all your seals.
