Item number 3,488, slide awnings.
Nothing wrong with slide awnings, they keep junk from accumulating on the top of the slides when they’re out. They also keep rain off the roof of the slide. When you pull in the slide, the slide awnings roll up and all the water squeezes off them. Know what else? They don’t completely enclose the roof of the slide; they just stretch over the top. When you roll them in, all the water squeezes off them, but the top of the slide room is flat. If it rains all night from that side of the motorhome, you may have no idea that about a gallon of water can accumulate on the top of the slide room until after you’ve pulled the slide in, been impressed with the amount of water squeezing out of the slide awning roller outside, and started to drive away. You might have no idea, until the rig goes a little off-level as you drive out of the campground….
What one may want to consider doing after a rainstorm, is put the rig a little off-level before pulling the slide room in, just in case.
