Ok. First - the original post (#1 in this thread) is NOT about leaving the FW tank full over the winter. Itís about the OP being (understandably) confused and concerned by the dealer offering to ďwinterizeĒ the unit while in for service and then picking it up to find the FW tank full. Winterizing has a pretty common definition to the vast majority of RVers and that doesnít include leaving any water in the unit. If this thread has swayed off topic (donít they all?), may I suggest your novel interpretation of the word ďwinterizeĒ was a strong contributor...
Second - as I acknowledged in reply #3 - given the OPís description of the details, I didnít think there would be damage to the tank. It takes a prolonged exposure to sub-freezing temps for 39 gallons of water to turn in to a frozen brick of ice - of course, the expansion of volume would happen before complete freezing but the point seems in these specific circumstances, OP would be best served by emptying the tank and repeating the full process correctly to avoid any water left in pipes or joints that will expand and cause damage if not addressed.
Third - as mentioned earlier, you have suggested there are varying models of winterizing. I canít argue with you on that. Just because Iíve never heard of it before doesnít mean it doesnít exist - but I literally never heard of multiple definitions of winterizing before. Methods? Yes. Blow out with air, flush with AF, some combination of both, use cheap vodka instead of AF - but all have the common definition of removing all water from the unit.
I canít know for certain but would venture your concept of some cases including leaving the FW tank full was novel to more than 95% of the people who read it here. Doesnít make you wrong/me right - Iíve just never heard it before nor could I personally see a practical use for such a scenario. If it works for you - awesome! Knock yourself out. If an RV dealer did that to me and said the unit was ďwinterizedĒ theyíd be paying for all the damages that caused.
Fourth - the snark was an obvious attempt at lightening up an unnecessarily contentious thread with some humor. You know - like we might do if we were shooting the breeze over a camp fire and having some fun - you know, when weíre not all hidden behind a stupid screen and missing 80% of the communication cues we prefer as human beings.
Last - hoping that clarifies for anyone reading this in the future. I agree with you - I donít like to leave things to chance when someone joins the forums - as I did when I was a rookie - seeking help and guidance. For future readers - it is my opinion that the most common understanding of the word ďwinterizeĒ means leaving NO WATER ON BOARD period.
Itís fine if others have differing opinions. You now have mine - likely worth everything you paid for it - and I wish you all happy camping, happy new year, and no ice damage in your future
