Suburban water heaters have an anode but the other popular water heater (Atwood) does not.
Here is a quote from TruckCamper Magazine:
"An anode rod is a solid metal cylinder that gets screwed into a water heater’s drain plug to prevent the steel water heater tank from rusting inside. They are made from aluminum, magnesium, or zinc, all metals that will “sacrifice” themselves through electrolysis and save the exposed steel water heater tank from a similar fate.
If you have a Suburban water heater, the tank is porcelain-lined steel and requires an anode rod to prevent corrosion of the steel tank. If you have an Atwood water heater, your water heater tank is aluminum and does not require one."
There are aftermarket anodes available for Atwood heaters.
