It's been my experience towing in snow isn't bad. The bad parts come after. The over zealous road crews polish remaining snow into a nice slick ice, and don't salt or sand it.
Late Dec 2015 I was in Los Alamos, hoping to move East along I40. However ABQ had received several feet of snow overnight and I 40 was closed. Worse yet portions of I 40 was closed because of flooding in Texas and Oklahoma.
So I took I 25 up to Denver and then no issues on I 80 East towards home.
I 25 around Co Springs was white knuckle at times. They were not requiring chain at the time. The real danger was a mix of very timid drivers stopping in the expressway and testosterone filled drivers on a mission to pass at any cost.
My trailer is tiny compared to yours. I don't think I would have to fortitude to take something with such mass out to play on the ice with the mix of drivers around the greater Denver area.
