In Texas when it snows, and it sometimes does, the ones you find in ditches and wrapped around phone poles are the transplanted Yankees who "know how to drive on ice and snow." The natives down here all hunker down and wait for the ice and snow to melt. And I say that as a transplanted Yankee who grew up in Alaska and took my first driving test on glare ice - and passed it too BTW.
The difference between snow and ice in Texas and snow and ice further north is usually the temperatures. In Texas the temp will be close to freezing, so there's usually a thin layer of water on the top and this is the most dangerous time as it's the most slippery. Up north it's either a lot colder so the ice and snow has more "grip" or it's above freezing and melting quickly. Whenever driving on ice and snow just be aware of the temperature; the closer it is to freezing the more dangerous it's going to be to drive on.
For a lot of the places in Colorado most of the snow will be on the landscape and the roads will for the most part be fairly clear and drivable. At altitude, like Denver, the snow quickly sublimates (goes from a solid to a vapor without going to an in-between liquid state) and the roads usually clear not long after the snow stops falling. Further up in the mountains though, like Durango, the conditions will be different and more postcard winter-like.
Like others here have suggested, I wouldn't want to learn about winter driving pulling a trailer of any length. Flying up and renting a car to see the winter scenery is a much safer approach. Learn to drive on the stuff in a car before trying to tackle it in a bigger rig.
Oh, I did do Monarch Pass last spring in my RV towing my Jeep Wrangler. Snow and ice on the roads, chain laws in effect and I had regular tires and no chains. Didn't have any problems and didn't get caught, but I'll admit it wasn't the smartest thing I've ever done in my life. It's pretty close to the top of my Stupid List.
