Pretty much.... don’t forget outside shower if you have one.

And the low point drains.

Dont forget the icemaker and fridge water if so equipped.

Also the sprayer for the toilet if you have one, but otherwise your pretty much spot on.

?Is the walmart antifreeze ok

[NevadaNick]

Yes

I don't know if this applies to your unit, but our water connection has a check valve at this hose inlet. While the pump is running I pull that little screen and press that valve to release what water remains there. I get a maybe a quart of water before it runs pink.

My Kodiak Cub has a built in black water tank flush system. I connect it to the house water output and flush it as well.

Don't forget water hoses and filters. They will probably not burst, but will deteriorate faster when water is frozen inside.

Any containers stored in the TT with water also need attention.

I wish you good luck and happy trails ahead!

A couple of things I would add for you is to pour some antifreeze down the drains to make sure you get some into the P traps. Plus leave some in the toilet bowl to keep the seals from drying out on you.

I suggest blowing out the black tank rinse. You can buy an inexpensive adapter at Wally World (under $3) and use low air pressure to clear the line and anti-backflow valve.

What about a bidet?

Here is how I go about winterizing-

1)Bypass the water heater. I drain it after every use so no extra draining involved here. Just leave the drain open.

2)Using an air compressor set to ~45-50 PSI and a blowout plug adapter on the city water inlet, purge all the devices that use water until very little water comes out. Then pack up the compressor. You will not need it anymore.

3)Open the low point drains. Where they are and how many depends on your specific unit. My coachman has 1 hot and 1 cold together just behind the rear axle on the passenger side. Open the faucets while the plugs are out to allow the system to drain any water left. Once drained put the plugs back in. Find and remove the fresh water tank drain. Leave this plug out.

4)Put the winterizing hose in the bottle and start the pump. You may have to prime the pump a bit. Allow the pump to pull in the antifreeze. I leave the pump on and go to each sink and run it until I get solid pink. I usually catch what comes out and pour it back into the bottle the pump is feeding off of. Remember to flush ALL devices that use water. Sinks, toilets, ice makers, washer connections, outdoor showers. Don’t forget the shower hose. And one important one, go press the check valve outside at the city water connection and let antifreeze purge out. There’s a little section there that can trap water.

5)Use the antifreeze you have left and pour it down the drains to prime the traps. Also pour some in the toilet to keep the O ring wet.

Now your done. Go through and remove any items that would freeze and be damaged. Remember any appliances, like a coffee maker that would still have water in it.

Drive to Houston Texas and park! No need to winterize this year.
