A few observations (not to get people riled up).
1)
Let's see exactly what kind of damage we are talking about, what your model loosk like, etc... Right now, we're all just guessing based on word pictures.
2) Perhaps others have thought this, but it seems odd that one would buy a tent named "Safari" and expect it to handle snow loads. In hindsight, it would seem like something that would have set off some bells if I lived in a cold environment.
Again, not to get people riled up, but it does seem that many folks have used maggiolina airland RTTs without issue, so this particular situation seems like just an unlucky combination of multiple variables (wrong tent in the wrong climate, left outside, etc...). Perhaps it was an autohome canada issue in terms of disclosure at initial sale (who knows), but the title of this thread should be changed to include the words "Safari" and not just maggiolina. Otherwise, the thread implies that all maggiolinas have this issue, when it seems, it's really just a subset of the tents designed for hotter climates. I know you meant well to let other owners know about this possible issue, but now that we know some more, it seems like it's not all maggiolinas.
