For truck campers, there are two primary manufactures of hot water heater. Atwood with aluminum alloy tanks and Suburban with their steel tanks.
A sacrificial rod of either magnesium or aluminum or a combination of both are suspended in the Suburban water tanks.
The purpose of these rods are too slowly corrode away protecting the tank from rusting and being corroded. Anode rods need to be inspected regularly and replaced as needed.
At the very least, when you winterize your RV would be a good time to inspect and replace the anode rod.
