We too worried about hail, living in the Denver area.
Have you given any thought to storing it with someone in a mountain area? We were lucky to have friends in the Buena Vista area who are housing ours (now I think about mice!!) and the mountain areas are not known for hail. Plus we are able to get to the trailer in route to most camping areas that we frequent. Here is a quote from the Ft. Collins weather alert website:
In Colorado, hail is a regional problem.
It rarely hails in the mountains or on the Western Slope.
Hail severity increases as you go east from the Front Range foothills toward the Kansas border.
Just a thought. Later, Leigh
