I am thinking of purchasing a Dynamax Isata 3, yr. 2020. My storage building at the opening is c. 11' 2 &1/2" while the factor specs of the unit states: height at 11' 5'. Are there any suggestors with a suggestion where I might find 2 & 1/2" other than the tire pressure trick? Put another way, what might I temporarily remove from the top that would get me there. Once inside the barn, there is plenty of room.
