Thanks Tarawander. I am up here in Idaho so it does get cold!
I am aware of the low point drains on the Forest River products but I am not aware of any on my Lance trailer that I am getting rid of. Thanks for the advice and your time to reply. I may upgrade to a 6 gallon compressor only because it is a good opportunity to upgrade what I have!

I do the same deal, no air just A/F.

Takes about 20 min by myself.

Others will disagree, but I don't trust blowing the water out of the lines method. My fear is that water will somehow find a low spot at a tee fitting or something. My fear is the air will blow right by the low spot allowing the water to freeze over the winter.

I'm a pink stuff fan. My buddy with a Four Winds he's had forever only uses air and an auto tire dc air compressor.

I do blow my lines but also use anti-freeze with the winterization kit that sucks anti-freeze straight from the gallon jugs on the inlet side of the water pump. My unit takes less than 3 gallons.
A small compressor like this is what I use.
The smaller pancake ones like this would work too.

It sounds like their three camps. Those who use air only, those who use the "pink stuff" and those who use both. My plan was to use air followed by pumping antifreeze.

Wow, great info in here! I've always had my lines blown out by someone else because I never thought my puny 1-gallon compressor was big enough....I assumed you needed one of those huge ones.

And I'm one of those red antifreeze guys, can get 20-below here at 7,000 in the Rockies so don't ever want frozen lines. It does rinse out real well...just put a little bleach into the water in the Spring when rinsing it all out.

Just make sure to allow the air press to build up between blowing each faucet. Use 30-35 psi at the compressor. Blow from top, shower and sinks down to outside shower and drains. Leave drains open on completion.

Blow all my lines out first and then pump in antifreeze.
