Commonly known as the 'water heater'.

OR Cold water heater as it heats cold water initially

Even Hot water heater as it reheats 110*F water which is considered hot

All the same and folks know what is what

Brand/Model is more definitive

2016 Winnebago Minnie Winnie 22r. Draining and removing/replacing the Anode Rod from the water heater.
1) I am having difficulty when looking at the electrical panel which breaker disconnects the power to the water heater. 1-6
2) Is it one of the breakers I switch off? If so, which one?
3) Or do I pull one of the fuses? If so, which one? (one is marked "tank heater")
4) Is it absolutely necessary to disconnect the electrical power before I drain the tank and remove the old Anode Rod?

The handwriting on the panel is atrocious and at age 69 I don't want to create problems for myself by being impatient.

This is my first RV, 1 year now, bought used 5/21 and am working my way thru a list of stuff to check and make sure it is in good shape.

And yes, I have read the Manual and instructions from Suburban for the model SW6D Water Heater. Checked also on YouTube.

To make sure that the electric element is off just unplug the RV. Don't start a genny, though.

YES one of those 120VAC Circuit Breakers is for the WH Element. Element is 1440W and typically uses a 15A Circuit Breaker
Which ONE????

3) Or do I pull one of the fuses? If so, which one? (one is marked "tank heater")

12VDC Fuse for 'tank heater' would be for heater pad on waste tanks OR could be for the 12VDC uses for LP Gas circuit on Water Heater

4) Is it absolutely necessary to disconnect the electrical power before I drain the tank and remove the old Anode Rod?

It is BEST to have the Individual 15A Circuit Breaker Open when WH Tank is drained.
If you can't properly ID which Circuit Breaker is for the water heater you can verify the AC On/Off Switch in outside compartment is OFF....Lower Left Corner behind/below gas valve

Voltmeter.....remove the 'Push To Reset Cover above gas valve
Under that cover are 2 sets of t-stats
120VAC...Left side Black Wire
12VDC ...Right Side Red Wire
Turn WH on using AC....verify you have 120VAC at the Left set
Then Have someone open each CB one at a time and ID which one drops AC to set of AC T-stats
Clearly relabel the CB.........

DC Fuses
Turn on WH using LP...verify you have 12VDC at the right set
Have someone remove DC Fuses one at time and ID which fuse drops DC to set of LP T-stats
Clearly relabel the DC Fuse.....

Man, I am having a heck of a time removing my Anode Rod from my Suburban Water Heater. Obviously the previous owner had not done so (2016 model year) and now the visible threads are rusted. I've soaked the threads for a couple of days now in CLP gun oil, WD40, Mineral Oil. I've taken a small wire brush and have worked the threads that I can reach. Tomorrow I am going to break out my powder blaster and see what amount of rust I can blast away. Any other hints out there?

Cheater bar
Impact wrench
Tap the head lightly with hammer
Sometimes trying to tighten it can break it loose form the rust/corrosion

Just remember the tank is Steel & Glass Lined so don't go whacking it with heavy hand

X2 on the tighten first . Just a good bump . All you need is to feel a slight movement .

Sometimes a good smack with a hammer on the wrench handle provides enough shock to break loose the threads .

Good luck .
