Our first trip in our Class C was in February to Orlando. We got caught in a snowstorm that followed us South for a while. Stopping in Georgia we still had snow on the vehicle, and once in Florida got some strange looks from all the salt spray on the RV.
Full tread depth tires and almost max weight you could accelerate as hard as you wanted to, no wheelspin. Easy to overdrive due to this so be careful. Stopping and steering will be a different story than accelerating.
Most RVs are white, so if it's snowing, keep your lights on so everyone can see you.
We had heated tanks, no basement, so we kept the heaters on after filling each tank with a gallon each of RV antifreeze. We used the toilet and sink/shower as normal on the way down. Drove straight through, and emptied black/grey once down there.
Kept the house furnace on. Did a good job, nice to come back to a warm RV after stops. You won't lose too much heating shutting down the engine and coach furnace at fuel stops. The cab was not well insulted. I imagine if camping in the cold using a heavy blanket of some sort to separate the cab from the living area would be of some benefit.
One thing I should have done, is wash the RV better once we got down there. Not so much the outside but underneath. Our first trip ended up causing some instant rust on several surfaces under the RV.
As several have said, if you have the time and it's too rough out find a secure place and wait it out.
Nebraska to Michigan. Once there we are staying with family.
That could be a bit of a challenge if mother nature doesn't cooperate. I personally would buy a set of " Z cable chains" just to be safe. They install easy and aren't very rough to ride on if you need to use them.

Yep, those cable chains can be a life saver, getting you that extra 5 miles or so at 10mph. Although since you have your house with you, the better part of valor is to just find a level spot and shut it down. Whatever you do with chains. Don't blow one and keep driving, it'll tear the heck out of your house. Yes even those lightweight cable chains. Don't run them broken.
Doing what you are talking about, it could be mighty crowded. 8-10 people in one coach and all.
On this end of the state they have to shut the interstate because of blowing snow fairly regularly. Of course you'd still be better off than the same head count in two 4x4s trying to survive. Someone would probably take pity on you and allow you to plug in. Maybe even 'nose' you into a machinery shed.
