we had the same problem with our sun-lite tc recalked the window and it still leaked so one day while driving in rain stopped got in the camper to check it out and found the problem their is a drain slot cut in the botom of the window frame to drain condensation out of the window frame to the out side of the camper high preeure wind was blowing water through the slot and on to the carpet so i roled up a paper towel and laid it in the track it keeps the wind from blowing the water out of the track and when enough water builds up in the track it drains out like it is suppose to problem solved.
