2019 Thor 22e Chateau Winterization advice

[Lorenzo]

Greetings,

Wanted to get some more info on winterizing my 2019 22e.
Does not get much below freezing where I am at off the coast of Washington State, but want to get a jump on this just in case its a colder than expected winter.

I know I need to do the following:
-dehumidifiers
-drain water tank
- drain hot water tank
-empty grey & black water tanks
-periodically run the generator
-Clear water lines
***my main question is how do clear the lines.
I see there are knobs on the blue & red water lines in the back underside of the coach near the grey water tank and in fresh water tank area.

Also what temperature should I try to keep the inside at?

If someone could point me towards the most efficient way to do that I'd greatly appreciate it.

If you are storing the coach unoccupied, I would caution adding heat inside. When it is cooler outside and you heat the inside of the coach, condensation forms creating a potential mold issue. Long term heating requires dehumidifying.

But if there is no reason to add heat... leave it as is.

As far as winterizing the water system, there are MANY posts/threads about "blowing out" the lines with compressed air. You will also find lengthy discussions about the merits of using RV antifreeze... the pink stuff.

Thor has many COMPLETE guides on winterization for every coach they produce. If you have an owner's manual, consult it for details. That way you KNOW you will be doing it the way the manufacturer intended.
