It depends on whether your slides have toppers. The folks from whom we bought our RV kept the living room slide out all the time at home. The rig hadn't been taken out for at least one season before we bought it.
That side if the vehicle faced south on their home-site. We noticed that the front edge of the topper was frayed on our walk-around, but didn't realise, until, at a campground on our first trip, that it was completely rotted away. Rain came pouring into the cabinets inside the slide-out. Fortunately, a Costco-size package of table napkins soaked up most of it.
Replacing the topper (and the one on the bedroom slide) set us back about $800. Eventually, I had to build a new set of cabinets due to a mold infestation caused by the water.
Just a little side note on slide toppers. We just replaced the canvas on our slide topper. $150 for a large 12' x 42" slideout. It's a really easy replacement, took 1/2hr.
Also the slide topper isn't the primary waterproofing.
