I've been stuck for 22.5 hrs + while going across WY in Sept. 2000
Freak storm, but crippled the entire state!!!
I was stuck with 5 guys in a '94 crew cab Ford after just grabbing the bag of cloths that I had still not unpacked/washed from my last 2 week job in Hawaii.
It was miserable and cold to say the least, but I thanked God on several occasions that I wasn't driving!!
This was around 10+ years before ever purchasing an RV, but I can see where it would be a problem for one who had tried to venture at this time of year!!!
Check the road conditions often and use caution while traveling through this state in early winter and don't put it off until it gets too nasty out to travel
