For the past several years I have been using a porta-shelter to store my 1900SR. In past years I have added extra bracing with 2x4s to ensure the snow loading did not create a problem in the winter. Well needless to say, this year I forgot and paid for it. Here are the pics of the shelter after 18" of snow. I was out of town for a sick family member and didn't get the snow cleared off.
No damage to speak of after clearing the snow, but I got lucky it didn't smash the glass.
Looks like I will be splitting the cost of shrink wrap equipment with my co-workers next year.
Lesson learned! I hope others can learn from my mistakes.
