Interesting you should post this . We have friends on a extend tour of the western US right now. They towed over Wolf Creek Pass this weekend in a snow. Small trailer towed with a Tacoma. She said it was white out conditions most of the time and they were barely moving, but afraid to stop for fear of getting snowed in up on the mountain.
The last time we crossed the Pass, we were heading into Pagosa Springs. Our friends were headed the other way.
