Problem winterizing 2019 Thor Four Winds 26

I have been enjoying the excellent information for awhile now but this is my first post so thanks in advance for any helpful info shared.

I cannot find any info on the proper way in winterinze our Thor Four Winds 26B. Our Freedon Elite had a dedicated suction tube to the pump. There are two similar tubes, one marked with red tape (hot side?) under the sink. Somewhat difficult to get to with a gallon to the pink stuff.

Any guidence would be appreciated.

I have a 2018 26B. There are three valves under the sink that I switch to bypass the hot water heater. Under the forward bench seat I can bypass the fresh water tank and connect my own fitted hose to draw in rv antifreeze using the fresh water pump. No way I would attempt to use their hose under the sink....

Most big box stores (Lowe's, Home Depot) sell poly tubing by the foot. That's where I got mine.

Is your water heater tankless?

My 2021 26B doesn't even have the hose under the sink. It's under the forward bench seat. I added my own extension to it to reach the jug, then it went smoothly.

I went to Home Depot and bought a plug and a couple feet of hose. Pretty simple and inexpensive, works like a charm.

Look for a suction port very close to your water pump. It will likely be a clear poly length of tubing which tees into your pump plumbing. It will have a screw-in plastic plug.

I made up my own extension:

I removed that plastic plug and made a trip to Lowe's. I purchased a threaded adapter (same threads as the plug) which I could slide the length of tubing onto, and secure with a stainless clamp. I use that "extension tube" only to add RV antifreeze, then replace the plug.
