Steve, although some members of this forum are fortunate enough to have a garage which can accommodate their trailer, I think very few RVs of any kind are stored indoors over the winter in this area - and we do get real winter. If there is no water in the plumbing, and snow loads on the roof are managed, I don't see a problem.
My B1700 has probably never seen the inside of a building, other than when it was made and when it has been into RV dealerships (or car washes) for maintenance. I have an open-sided shelter - still to be assembled - and if the
Boler fits I'll put it under there; however, there's little chance I will ever have a garage for it.
