Winterizing 2025 Coleman 17R Camper

ᎣᏏᏲ. ᏙᎯᏧ? Hey, welcome back!

I needed to winterize my camper and had missed my window to take it and have it done. It turned out that the cold weather came in a few weeks sooner than it was supposed to. In any case, I felt like I had to winterize today instead of waiting as the temps were going to drop below 22F. Last year, we though the camper was winterized and ended up spending $1000 on a new heater because it had some water in it. Why they make the heater so non-insulated is beyond me, but it’s not a camper for 4 seasons… still…

Below is the layout of my camper direct from the Keystone site here. I’ve marked the steps I took based on the video at the bottom of this post.

I’m not sure where you *should* start, but I started with A.

A – the lower drains for hot and cold. I opened the valves to drain any additional water out.
B – I made a makeshift air-chuck-to-hose connector which cost me $17 using parts from Ace Hardware. I used a 1/4″ chuck connector threaded to a 1/4″-to-1/2″ reducer (expander in our case) then a 1/2″ to 3/4″ hose connector with valve. I used pipe tape and it worked quite well. You can also order one from Amazon it’s called a “blowout fitting” or “blowout adapter.” This is the one I ordered and was also about $17.

C – I opened the valve to drain the freshwater tank. I had about 1/4 of a tank so it didn’t take long. Luckily, we had already emptied and cleaned the black water and grey water tanks.

D – Some of the videos said to take out the “water heater anode rod” which I didn’t have. We’ll come back to this area later.

I went back to B and opened the valve then went inside the camper and opened E and F and pressed the foot pedal for G one at a time then shutting them off. I then did this 3x until I felt like there were no further mists or sprays coming out of any of them.

I then went to the freshwater tank at H and uncovered the input tubing.

I then turned the valve open O so I could pump the antifreeze in.

I then turned on the water pump and then went to E and F and turned on each valve until the pink antifreeze came out. I then pressed the foot pedal on G to see pink antifreeze come out.

I then covered up the intake hose and left all of the valves open.

I then poured some antifreeze into the sink drain and shower drain to the P-trap and poured some into the toilet itself without pressing the footpedal.

I then cleaned everything up… just kidding, I left everything the way it was. I’ll clean it up in the spring.

Until next time. Dodadagohvi. ᏙᏓᏓᎪᎲᎢ.
