Due to school and family, I have not had the camper out since last fall. I graduate this week, and I started getting everything ready to go in a few weeks. When I went to let the bunk ends down, the seals were stuck and not letting the end drop. I had to tug on it, and on one side, it torn a slice about half the size of a match stick on the outside edge about 1/4 inch long.
Even though I am not using it, I am still washing and cleaning the camper about 4 times a year. I noticed some dirt buildup on the seals after I let them down, and I think the buildup was part of the problem. So this time, I took a rag and put some Mothers VLR cleaner and conditioner on the seals before I put it up.

After wiping everything down, I got a load of black crude and plain dirt off on my rag.
Does anyone else clean and condition their end seals?
