You can safely wait until the day before a frost/freeze warning... Beyond that it's your risk...

Each coach model is different as to where water lines run... If they are in heated area... If you are running the heat... (A separate space heater may not heat a 'wet bay' that the coach furnace would.)

If you use the air method of winterizing, simple and cheap to do multiple times in a season... Takes me no more than 15 min to do and only about 1/2 gal antifreeze.
Drain hot water heater, valves to bypass, hook up air (50 psi max) to city inlet, open all faucets hot and cold one at a time until only air comes out - don't forget toilet, outside shower)... Pour some antifreeze down drains...done..

Use RV anytime... Just repeat when done.
