I have not researched it yet but was sort of wondering what most folks due to winterize.  I m guessing keeping the wet bay from freezing is more designed for those that travel during extreme cold vs winterizing protection. We personally like traveling when its cooler but not Frozen, was thinking just like our 2nd home in the mountains, I would drain all liquids and use the pink stuff in all the traps.

If you have an AquaHot and a washer/dryer, you should run pink stuff through all plumbing including the AquaHot (or risk a $10K rebuild cost) and through the washer/dryer to properly winterize.  You cannot simply drain the lines as there will be water left in places like the AquaHot coil, the washer, the fridge icemaker line, and the shore water hose reel.  The AquaHot and washer winterization warning is in the owner's manual.

The low point drains on the coach do not drain the AquaHot, the washer, or the icemaker line.

Also run pink stuff through the toilet, including rinse wand and flush with it (via the water pump to get all lines) if you have a VacuFlush toilet.

It takes about 5-6 gallons and you can suck the antifreeze in via the water pump with a short hose adapter.  For the shore hose, unfurl it and let it drain fully. 

It sounds involved, but it usually took us less than 1/2 hour and doing it on the last warm-ish, calm day after the last use and before the first freeze was a routine process.

Was my plan, I sort of do similar with a house we have in the Smoky mountains. There I drain all lines, use air pressure to also blow the lines, then leave the ends open, but then only use the pink stuff in the traps.

Instructions for the AquaHot especially (ask Rudy) and Splendide will tell you blowing air through is inadequate to protect those, so just don't neglect to run antifreeze through them.

Point made,

IF one were to pink stuff the entire rig, What stops any of the pink from making it into the under the sink water filter?

You remove the filter and housing and replace it with the bypass plug.  Everpure Water Filter Bypass Plug

Rudy,
Good point to point out.

Lon,
Have you maybe drunk too much of that  pink stuff?..."tastes good too"....just kidding good humor.
20 gals vs others comments of  average 5-6,  you must have way more fluid paths than the average system?

Roger,
Thanks for the PDf and all the details.
I like your idea aabout the disconnects on both the water pump and the previous comment about the wet bay Stat.

still between my 2nd home where I go through maybe 2-4 gallons a year, and this much for the rV, might as well buy it by the case if I can.

Eddie, it is absolutely necessary to run the Aqua Hot with the fresh water lines drained when stored in freezing conditions.  You can never ever drain or blow out the water in the bottom of the many fresh water loops in the heater.  Allowing the AH coolant to go below 32 degrees F will freeze the residule fresh water.  A $10,000+ mistake.

So, with the interior thermostats set to 50 degrees F and the basement thermostat set to 40 degrees F, turn on the electric element and diesel burner when below freezing temps are expected.  Open cabinet doors below the sinks to let warm air into the cabinets where the water lines are located.

As long as you have the grid power and diesel, you are good to go. If you loose grid power, start the gen.  As long as you have more than 1/4 tank of diesel you are good to go.  No draining necessary.

Hope this helps
