Travel by Motorhome in problematic weather should include this easy answer:
Maintain a day's supply of fuels.
Maintain a two day supply of water.
Have provisions onboard for three days.
Watch the weather carefully and do not push into a bad situation.
If the weather goes bad, hunker down where you are. It is called a "Motorhome" for a reason. Let them clear the roads and those that absolutely have to get somewhere go there. You can watch all this in the comfort of your chair while listing to the news/weather and drinking warm coffee (or other).
We used to do most of our traveling in the early spring and late fall. We often had to hold up for a day. Food can be harder to than fuels. Below freezing water can be an issue.
One year we were headed home after a family visit to the east and got stopped real late in PA. This was with two kids and in a car. We got the last motel room and the last pizza and counted ourselves very lucky. That was a real good lesson.
The fall of several years ago we might have repeated it in Iowa, but we got to a rest area as things were shutting down. We were ready. We sat in the warm coach for about a day and an half and were not displeased with out choice.
