I live about a mile and a half away from a horse club where many members leave their different type of RVs year round. They sit outside in all types of weather, including snow and ice storms. And I mean snow storms, like up to a foot at a time. And lots of ice storms. I have yet to see a roof collapse and have heard of no roofs leaking. Many have been there the 10 years we have lived nearby. Several of them are removed for summer trips.
And the many dealerships in this area (near Buffalo, NY) leave both new and used travel trailers, 5th wheels, class A, B , and Cs outside all winter long. In fact I have seen some brand new $300,000 units sit outside for two winters.
My 19 year old DP sits outside all winter with no problems.
