The Sacrificial Anode Rod
Part of a truck campers’ preventative maintenance program should be to check regularly and replace, as needed, the sacrificial rod in the Suburban hot water tank.

There are two primary manufacturers of water heaters for truck campers—Atwood with aluminum alloy tanks and Suburban with their steel tanks.
A magnesium or aluminum sacrificial rod is suspended in the Suburban water tanks.
The purpose of these rods is to slowly erode, protecting the tank from rusting and being corroded. Therefore, anode rods need to be inspected regularly and replaced as needed.
At the very least, when you winterize your RV would be an excellent time to inspect and replace the anode rod.
