I've done the winter driving thing as needed in the past and would do so as required in the future. Growing up in Western PA I've had significant experience with winter conditions and spent many years as a commercial driver also.
Since retirement we don't have any tight schedules and are far more flexible than before and would chose not to travel in poor weather. It's nice to be flexible with our plans and we spend winters where no one knows what a snow shovel is for or how to use one.
My biggest concern today would be as mentioned by many previous posters, the snow melting chemicals impact on my coach. The salt brine many states use today is even harder on vehicles that the plain old salt they used for many years. It corrodes things badly and very quickly. I'm not sure you can get it off quick enough to avoid at least some rusting from its effects. Simply nasty stuff and none of the states that use it seem to care how much vehicle damage they cause.
