Haven't been really worried about the snow on the roof of the Avion this winter. I cleaned a couple of feet of the crap off the old house so it doesn't fall in before I tear it down. My water comes from the house, washer a dryer is in there, plus storage. The camper I was thinking about doing this weekend. There's enough heat loss through the roof to melt it and I thought maybe that melted snow could cause an issue. . . . This morning I went to open the door and couldn't, freaking ice on the step. Didn't want to force it and bend the door. OK there's an emergency exit window, I'll just crawl out through that and chip ice. Well that didn't work, more damned ice! But I could get under that with a screwdriver and chip it. Then jump into about two feet of snow and made my way round front and chipped that ice. Yeah I'll be cleaning the roof today!
