I can't imagine much more than 4-6" of snow on the top of that before it starts becoming a problem. Only because that roof pops down to store it away. Perhaps you could use a broom stick in the center if you going to be in heavy snow and just every so often pop the snow off it. You should send 'Alex' (the person you saw) a message in the contact us form on bottom of this site.
Looks the fabric used and window size/shapes.So how are these different from Shiftpods?
