I tackled a little maintenance project on my RV. I noticed that the slide wiper seal on the top was completely falling apart due to its age – this trailer’s almost 14 years old now. I had previously replaced the secondary bulb seal a couple of years ago because it had failed from too much sun exposure, but the more shade-protected top seal now needed attention, too.
I ordered a new set from AP Products, specifically a 35-foot-long seal, which matched the dimensions I needed for my Keystone Cougar 2011. The installation was quite simple; the old seal just pulled off, revealing a rail where the new seal could press fit. There were six screws at the ends to secure it. I measured carefully, cut the new seal to size with serrated scissors, and installed it by pushing it onto the rail.
It went on smoothly, especially since I did it when the rubber was warm from the sun, making it more pliable. I used self-tapping screws to fasten it down, ensuring a good fit. The whole job took about an hour, including some cleaning, but could probably be done in half that time without the extra work. It’s great to have this maintenance task out of the way, leaving me with some extra seal material for future repairs. Remember to match the dimensions carefully if you want to do something similar.
