Can you? Yes.
Will it be comfortable No.
RV's are not insulated. Windows are not thermo pane and they have a lot of windows.
I was in Florida where it just got close to 32 degrees for a couple of days. It sucked. You have to cover your windows with insulating material which then you can't see out to keep warm. Couldn't fathom RV'ing colder than that and with snowstorms.
And in my case I have a MH with a huge windshield that also has to be covered to keep the cold out and had to insulate all three of my roof vents because the are just a plastic lid not sealed etc etc.
You also have to winterize all your water lines and hot water heater.
Soooo the die hards that winter camp will say its great, but for me I found it not much fun. :C
