I have noticed driving around that many people have their slides open while camper is not in use. Perhaps they are using them but I don't think so. Curious about opinions on this. I would think it ...
My thoughts are when they are in birds and other critters have fewer places to get in or build nests. Water has less small openings to come in through. In most cases but not all I have access to areas I need to get to inside. Access to storage bays is easier when slides are in. May be different with a TT.
