Many others as me, are not fair weather campers, but camp in all weather.
I've camped many times with my 2 pop ups in the winter and yes, they got about 3 inches or more of snow on them. Just knocked it off the bunkends. I even was able to fold it down with snow on the roof. :E Made for it, no warnings in the manual. Just watch out when you get into the teens as the plastic windows in a pop up can crack.
OF course these pop up campers are made in Indiana which has all 4 season, so campers here are designed to be used where there's 4 seasons. Trailmanor is made down south in Tennessee where they're lucky to even see snow or ice. Guess they design them to only be used in the south.:R
Now all campers and even homes, warn of excessive snow loads on the roofs but Trailmanor is saying you can't fold down your camper with a light 1" snow dusting. In my area, that means I'd never be able to go home from a campground in the winter! Or you would have to carry a ladder, broom, ice chipper and scraper and hope damage isn't done to the roof removing the snow and ice!!! Ridiculous!
All I'm stating is that this camper can't be used in the winter when many people do use their campers.
