My 19 Rockwood has an anode rod in the hot water tank.. My 03 Prowler did not..
I never had an issue with that 03 hot water tank in the 16 years I owned that trailer..
Now, I gotta check the **** thing and then buy a new one every year or so if I use magnesium or use aluminum and then risk the whole hot water tank going bad... Great... Wish I had an Atwood in the Rockwood... :)

Should be draining/flushing tank at least once a year.
Gotta remove anode rod to do that so it's not like you have to do an extra step.
Anode Rod is necessary to be sacrifical so that the STEEL tank doesn't rust away.
Suburban uses a STEEL tank that is sprayed with a glass lining....but glass lining does NOT fully cover every nook/crannie inside the tank and does have cracks hence the NEED for the sacrifice of the anode rod.
Atwood uses an aluminum tank that has a zinc cladding on interior of tank that acts as the anode rod ----
Per Atwood:
"Atwood water heater tanks are constructed of a high strength aluminum.
The interior of the tank consists of a .0015 thickness of type 7072
aluminum (pure aluminum and zinc) that is fused to the core during the
rolling process. This material protects the tanks from the effects of heavy metals and salts found in waters throughout the country.
It is anodic to these heavy metals and acts much like an anode in a steel glass lined tank except it will last much longer.
Aftermarket Anode Rods are not required and should not be used and will void warranty."
