I am sure this has been discussed before but I can't find it. We have a new 2021 Fleetwood Bounder 33C and plan to use it during the winter months weather permitting. We live in the Boise Idaho area so we do get freezing temps and snow. The question I have is would blowing out the lines with a compressor, dumping the fresh water and holding tanks, drain the water heater and adding RV antifreeze to the drain traps be enough to protect water lines? If at all possible I would rather not have to fill the lines with RV antifreeze because it would make for faster prep time for a trip.
Also I would blow out the combo washer/dryer and we do have the residential refrigerator ice maker turned off since day one.

Any thoughts would be appreciated.

Thanks Chad

I looked the monthly average temps for Boise. Not too cold.

I live in TN and have winterized my Class C & Class A as you describe using compressed air and RV antifreeze in the pee traps. Never had a problem.

Don't forget to blow out the lines to/from waterpump. M

And if the water pump has a strainer , take it off and drain it , then run the pump dry . Your water system may have any number of slightly used sections so go through carefully when blowing the lines for the first time .

Low air pressure but lots of time and volume of air to do the job right.

We have a 2014 Fleetwood Southwind and personally, I am not content with just blowing out the water lines, even though many have had success with doing so.
I always drain the lines, and then add RV Plumbing Anti-freeze to ensure there is no low lying water.
Don't forget to release the pressure in the "city water" intake behind the screen and remove the water filter.
I use 5 jugs @ $3.00 each, which for me it is cheap insurance during long periods of freezing temps.
We leave Ontario in January and head south, and wait until we hit Florida before de-winterizing.
The process is quick, easy and I never worry about afterwards.
