The last time we had ice/snow, I forgot to pull in the slides. All was fine as the snow/ice slid off. I have awnings on my slides. The last RV I had didn't have awnings and I would get a step ladder and push broom and clean as best I could. This worked with snow/ice leaves, wallnuts, etc. Didn't have problems either way. So, if you have awnings, you should be ok. But, if you can rest better, bring in the slides before the snow. Enjoy the winter as it is beautiful.
