Robin gave you good advice.
I would add one thing. If your trailer has brakes
and you need to put chains on you TV you better put them on the trailer.
If you stop with chains on the vehicle and not on the trailer chances are the trailer will try to pass you. I know from experience.
Best advice is if you don't have to drive in snow and ice,don't. Wait for the plow to come by.
Take your time like Robin said.
One other thing, If you have never installed chains practice putting them on and fitting them now while the weather is fairly warm.
I also carry a small tarp to keep out of the snow while installing the chains.
Have a great trip.
