I had a slide on my small hybrid years ago. Went fishing in Montana one late fall and we had a little snow the first night. It warmed during the day and then we got another inch or two. It warmed again and didn't snow any more. When I got ready to leave I had an ice block on top of the slide. Warming and freezing over a few days was the trouble. No ladder, but we did still have a few rounds for firewood and that worked. Sold the trailer shortly after that but if I hadn't, I would have installed a slide topper.
