That is quite a comprehensive list. Thank you for posting it. John does not want to put pressure on the system by blowing out the lines so we follow the winterizing video Earl has on the Phoenix site. This will be the first long freeze time that we are not in the rig so I guess time will tell if our system works. We have stored up to a month of freezing weather and have been living in her for shorter freeze times where we do a partial winterization to protect the Macerator and tanks.
We also pull out our more delicate electronics and all little batteries - weather radio, walkie talkie, GPS, remote thermometer, battery charger with batteries, little solar charger, etc. We have a little bin they live in until they go back in place.
And I pull the mattresses a couple inches from the wall to avoid condensation there and open one vent a bit.
