We live in Florida, so have never needed to do this until now. We're leaving our TT in Colorado at 8,300 ft elevation, so very cold at times, for several months. Leaving it at a lower elevation wouldn't solve the problem, still very cold, and my family's place is free.

I've researched it, and could do either the antifreeze method, or the compressed air blowout. One site said the blowout method is only recommended for moderately cold areas, but I'm not sure why that would be true.

Please let me know your thoughts on this, plus any tips you may have for either method.

I will be buying a cover for it, and will cover the tires. It will be stored for 10 months, October through June. Any tips for this lengthy storage also appreciated.

Thanks!

Id say blow it out then run antifreeze through it. It takes 20min and only cost a few dollars. Cheap insurance. then you don't have to worry about it when your 1000mi away and hear about a cold snap in colorado.

Cheap insurance is right when you do both - blow it out and run antifreeze through. We used to just blow it out. One winter, we forgot to open the toilet valve while running the compressed air in and it cracked that valve. Now we blow it out and run the antifreeze through holding that valve open to run till we see the pink stuff. The only thing I don't like is the smell of the antifreeze in the spring. No matter how much we flush, there always seems to be some left behind.

I would never want to trust the blow out method. I am not sure you can get all the water out of every location. RV antifreeze works well if you follow the manufacturer's protocol. The cost is minimal.

20 years and less than 2 gallons of antifreeze to winterize.....air vs antifreeze? Neither freeze but I'll take antifreeze.

Make sure you drain water heater and bypass it during the process.

I've always used the compressed air method, and it works fine if you take your time, and is easier to dewinterize come spring. That said, both methods are perfectly effective if done properly.

The idea that compressed air is only valid for moderately freezing temperatures is absolute foolishness. Water freezes when it's below freezing, and it doesn't freeze "more" because it's far below freezing. Either the plumbing is (basically) free of water or its not; if it is, you're good for any temperature, and if it's not, you should avoid conditions where it would freeze and burst fittings, etc.

I’m not quite sure how forgetting a step has anything to do with the methodology. I’m pretty sure if you’d forgotten the toilet using pink it still would have frozen and cracked.

In my case pink stuff is completely unworkable, I winterize / use / winterize numerous times per winter. With air all I have to is switch on the water pump and open a tap. No muss, no fuss, no smell. I can (and do often) literally do it going down the highway.

Your saying your water pump alone flushes all lines of H20 ?
City water hookup ?
Low point drains ?
Outside shower ?
Water heater ?
Traps ?

There's more to this story.
