Winterizing 1999 Rexhall Roseair

[Skook]

Hey all...
I have a 1999 Rexhall Roseair.
I just relocated it from California to North Dakota and need winterizing tips, specifically how to bypass the freshwater tank to get antifreeze into my lines and traps.
Any advice or valve location would be appreciated.
I have all the manuals and of course Rexhall is not in business anymore, but the manuals are vague and nobody answers the phone in the empty building LOL.

Any advice or valve location would be appreciated.

It may not have a special valve to make adding antifreeze less work as that is one of the things that have become far more common now than was the case back in 1999. If you have one that valve would be located between the fresh water pump and the water tank and on the suction side of the pump. It will look something similar to this picture, if you have one.

You should also have a water heater bypass so that it can be drained and left empty when you add antifreeze. That will be at the back of the water heater and look something like this.

Neither one of these always look the same but should be similar. If your RV doesn't have them, it isn't difficult to add either of them and kits for them are readily available.

Thank you, sir!
I appreciate you taking the time to answer my conundrum.
