Now the one thing you have to consider is what you do after you have driven in the snow and camped. What about the snow accumulation on your slides? Do you remove it before you retract them? My coach has the awning toppers and I just slowly retract the slide in small increments, and this allows the snow to drop off. What about the snow accumulation on your roof? I know some states do not like it if you head out on the road with big hunks of snow/ice blowing off of your roof on to the vehicle behind you.
I think I mentioned that I have needed my chains more in the RV Parks that can't deal with the snow to clear their roads. If you are traveling and you are expecting more snow, by the time you want to leave, I would suggest putting on the chains when you get a chance rather than to park, get a foot of snow, and then realize you have to put on the chains to get out of the RV Park.
Basically you learn all of these things with experience but these are just some things to consider. Every coach is different and have different requirements.
When we are traveling in the Winter, I never Winterize the coach. I keep my fresh water tank as close to full as possible. I hook up to electric but do not hook up to water or sewer except to empty my tanks or to top off my fresh water. If it is really going to get cold, like below zero, I run an extension cord and put a 100 watt incandescent bulb in the wet bay near my water pump. This works fine especially since we very seldom run our propane furnace and prefer electric heat inside the coach. This has worked well for us down to -5, which is the coldest we have camped in.
