Winterizing --- Antifreeze or blow'em out??

[Grady23]

I have a 2010 Cougar 318 and in the past have always used the R/V Antifreeze in the unit. I have a compressor which can be dialed back for a reduced pressure. Do I run the risk of leaving small pockets of water in the lines or does this method do the job? I plan do drain everything before I use the air.

I do both only because I have a water valve on the toilet that is really hard to get all the water out with air. And the valve is cheap plastic and a pain to replace and $40.00. So I blow it out with air and put in pink stuff. I dial down air compressor to 35-40 psi.

But most people do one or the other IMO
