Some good advice above. The main thing is that you have a lot of rolling weight, kenetic energy as it were, so you develop a feel for slippery driving which includes making all changes of direction, speed, or braking in a slow, calculated manner. The one thing not mentioned above is the huge variety of snow conditions. In VT i imagine it is rather fluffy and easy to motate thru drifts but easy to spin a wheel in. Here in the Sierra Nevada we have a texture called, "Sierra Cement" which describes snow with a very high water content. We get a lot of our snow at 34F to 28F and It ices up very easily.
My experience with dualies on snow is not a good one, even with snow tires. There is just too little ground pressure.You will have lots of ground pressure.
I don't see any problem for you besides fear. Just make sure the pressure is up on your tires and go....slowly.
Here is a little TC winter driving down our lane the week we moved in: March 2006. As a disclaimer, I did have to winch when the snow got deeper than 4 feet, just up the road on the unplowed part.
