Winterizing steps question

I came across a "how to" winterize guide on Camco's website last night. It said to drain the hot water heater LAST (doing all other necessary steps first). I have done it opposite by draining the hot water heater toward the beginning of the process. Why does Camco say to drain last? Does it really matter? Thanks!

You might want to drain first and last. Drain first, put drain plug back on, blow air to clean all the lines which will force a certain amount of water back to the tank. Then drain tank again.

Well, if the winterizing valves are turned correctly, the tank is isolated from the fresh water system. Once drained, it remains drained. I drain mine first.

x2 if this is done first find it easier than follow the items listed in this link.
You may want to go camping if it were to warm up.

FYI - The latest FMCA magazine just came out and it has a section on winterizing. It says empty the hot water tank first. I don't know if it makes a difference if you have a by pass valve but they may assume you do not and that might make a difference.

I always empty mine first. I can open the low point drains, isolate the water heater and then pull the anode and clean the tank out while the system is draining the pipes through the low points. Saves a little time and I agree with the others; when the water heater is isolated, it doesn't matter what winterizing method you use, air or antifreeze, it can't have any effect on the water heater...

I suspect that these folks that create these "lists" put the water heater wherever...it has to be either first, last, or in the middle somewhere, and the choice belongs to the list creator since, mechanically it doesn't matter one whit.

On my 1982 MH I drain it first then blow air then antifreeze. I don't see a way to get my anode out if it even has one. I think it is a Standard Brand but will look at it today.
I am getting it ready to head south.
May I ask a question while we are on the subject of water heaters? My water heater is propane, After driving lets say 1 1/2 hours I get to the camp site and the hot water is so hot you can't use just the hot you have to add a little cold water or you will burn your hands. How is it getting sooo hot.
No the water heater isn't on
Thank you, Tim
