ONLY applies to Suburban Water Heaters. Atwoood/Dometic water heater are not steel tanks and do NOT have anode rods. These should only be fitting with a plastic drain plug.
Safety Tip: Make sure you pull the lever on the blow off valve before you remove the Anode. Unscrewing a plug with 40 some PSI behind it will not end well.
If this deterioration is electrical based, does that mean that if you never use the electric heating portion of your water heater this would not happen?

Nope. It is the steel tank that needs to be protected irrespective of fuel source. AND only Suburban Water Heaters.
Would you suggest aluminum or magnesium for the replacement?
For none hard water areas the cheaper AL rod is fine. For hard water areas would recommend magnesium.
