Dick, no I'm not referring to the sealant around the window frame. On the bottom of the outside frame where the small sliding windows open there is a space between
window glass and frame. The space is on the bottom and both sides, The
weather strips that I mentioned fills in and covers/protects the sides and bottom
of the frame. The weather strips are only around the sliding windows. Our
trailer is a 2010- 3150RL, and I assume everyone has the same window that
have a small piece of glass at the bottom that slides open. Check the outside
of your windows where the bottom of the glass slides open.
