Camping world makes heated hoses (we bought two 15' lengths this year) and they work fine so you don't have to get out in the freezing cold and disconnect. I have a full set of chains in a bag in my warehouse in TX - had them 5 years at least while we were up in Idaho Springs and Evergreen living there. Never used them. The tunnel and I70 are maintained very well and the State keeps it clear unless it is blizzarding... We did get stuck in Eisenhower tunnel in the car once but that's another story...
