My seal that sets in a track slides when we are driving to the came ground. I checked it out and found that the seal was
staked on the ends with what looked to be a nail drove into the side of the camper. my seals are like sticky rubber and when I open the slide it sticks to the slide and pulls it away from the side of the camper. I am going to rub my seals down with silicone spray that is made to use on rubber, then i am going to install some gorilla duck tape 6 inches back from each end top and bottom this should keep it from moving. hope this helps Dale.
