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

I always blow mine out just for piece of mind but I never get any more water out after doing the following.
First I bypass my water heater by closing the valve. (some may not have this feature)
Second I drain my water heater by pulling the plug and then opening the pop off valve. (in that order or you will get wet HAHA!)
Third is the most important step IMO. Go inside and open all of the sink valves hot and cold. Shower, sinks, washer(if you have them you must unhook the lines going to the washing machine) and the toilet flush valve. I just use a heavy object to hold it down.
Forth I open my outside valves (outside shower , etc.) Once all of the valves are opened then I will remove the caps from the low point drains. This will create a siphoning effect that sucks the water out of all the lines including any low spots there may be.
Like I said before, I then reinstall the low point caps and blow air through the system. I never have any water left to come out but I gives me piece of mind.
I will then pour a few ounces of RV antifreeze in each drain to force out the water in the traps. A gallon of antifreeze will last me a few years.
Again, this is just how I have done it and have never had any problems. We only get into the teens around here with the occasional single digit or sub zero day. This may not work for everyone.
