If your seals are melting I'd figure out a way to keep them from being exposed to that kind of heat.
If they are sticking and looks as if they have melted I'd take a good look at the side of the slide. On mine there is an area next to the outer trim flange where it looks like the seal may have melted but it's merely where the person who installed the sealer/adhesive for the flange was careless and some of it extended out onto the side of the slide.
When closed the rubber seal would stick to the exposed sealer and eventually left a black one where small particles of the seal stuck. Some serious work with a plastic scraper and some "Goof Off" removed the excess sealer. Then applied some seal spray like pictured earlier and no more issues.
Another option is to take a cue from the tire industry. Back when tires were "Tube Type" regular talcum powder was used to keep the tube from sticking to the inside of the tire so it could be removed for repair if necessary.
Today's talcum powder sold in retail stores is really cornstarch which can be more like a glue so don't use that. Amazon (and perhaps bicycle shops) sells Tire Talc which is pure talcum powder. Apply some to a rag and wipe the surfaces of the seal that slide on the side of the trailer. This will help keep them from sticking, even in high heat.
