Winterization antifreeze intake line

[Thor_ID]

I am new to RV ownership. I just bought a brand new 2020 Thor Freedom Elite 22HEC. I have been reading up on how to winterize and most people recommend installing a pump converter kit to avoid having to put antifreeze in the fresh water tank. I noticed on my RV there is this capped off white tube connected right after of the water shut off valve coming from the water tank and leading to the pump on the other side of the dinette. Is this tube supposed to be where the pump would siphon from a jug of antifreeze? I bought this unit from camping world, is this something the dealer installs or does it come like this from factory?
See photo attached. Thanks!

If that tube is connected to the pump with a valve than yes that is the winternalization port. Put the hose into the antifreeze jug and turn on the put. it should only take 2 jugs of antifreeze to do you RV.

Also, look for the valve between the tank and pump and close it. This will cause 100% pull from the antifreeze jiug. Otherwise you will be pulling fresh water from the tank also and diluting the mix.

What those guys said!
I will add find low point drain for fresh water tank and open.

Great! Thank you I'm glad that's already there.
