Any tips? Insights?

Uncle has a 2011 or 12 Winnebago View on a Sprinter Chassis. Generally we store it in the warehouse for the winters with my cars. However they are using it at the end of this month for a trip to Florida and may use it again early next year. So the question is, why don't we just winterize it so it can live outdoors in the space he rents year round for it.

I know nothing of RVs but I know a good number of people on here have them and figured I'd ask you guys before I join an RV forum and display my ignorance

Is it as simple as RV anti-freeze in the water tanks?
