Have just become full timers. First winter in motor-home , presently in NC. Have have temps in the teens for several days each week for last several weeks. Appears that a snow storm is heading our way...
If it were me, I would bring the slides in before the snow starts and deal with it. The good thing about where you are is in a few days, it will be gone. The other thing is, once it stops, you will be able to put your slides out without any worries. The thing I would worry about is ice when the snow melts and then refreezes at night. It is a lot less trouble and cheaper to pull them in than deal with ice on a slide topper.
