I have done some cold weather rving, and as I understand the RV can handle it no problem.
When the propane heat is running there are vents in the plumbing area to keep the pipes from freezing but I would also place light bulbs in there. I have a heater pad on my fresh water tank from the factory, you might want to get one if yours is not equipped with one. Have a good ladder and broom on hand to keep snow off the roof. Be sure you have a heated water hose and that the water valve outlet is heated.
Lots of people do it. You might want to search IRV2, there are probably many threads
