Another thread noted the slide leaked when towing in driving rain, which may indeed have been a faulty gasket or some other malfunction.
this prompted a thought. In my past life with commercial cooking equipment, we were taught to leave all doors slightly cracked when the equipment was not in use to protect the expensive gaskets.
i try to do this with my 14dbs, leaving the windows basically hanging, to avoid compressing the gasket. On most all days I open them further for air circulation. Keep screens in use to prevent birds and insects from entering. As it is parked by my main home exit, when I leave I just go around and release them into a relaxed down position should it storm when I am gone
i also leave my slide open about 1" to not compress that really gig gasket when it is just sitting at the house
the entire camper is generally under a breathable gold line cover, which I also unzip a ton on breezy days to get good circulation on the camper. This keeps the uv rays off all gaskets and tires.
happy camping
