wow, 3 grand is a lot of money. My 18x48 high tunnel cost less than that.
If you can build your own structure, you will end up with more space for less money.
My high tunnel did get smashed by a winter storm, but we had about 8-10" of sleet that accumulated as a sheet of ice. The greenhouse you're considering is rated for 30 lb/sq ft of snow load, which is about two feet of snow or six inches of ice. So really big storms will still smash structures that are supposed to shed snow. My high tunnel looked like it was destroyed, but it just took a few days of work and about $30 of materials to put it back together.
