You are correct and I stand corrected. Thats what I like about this forum. The proper procedure/technique will be found eventually.
However, the main concern seems to be that the rod is installed without anti-seize and the resulting reaction with the aluminium causes difficulty removing it at a later date.
However, if my rod is depleted within one year then it is, in my opinion, serving a purpose and protecting something else from attack.
"Atwood Mobile Web Site Response
Anode rods are unnecessary in Atwood water heaters.
Even though manufacturers of those devices claim they are made for our
water heaters, we do not advise using them.
"The Atwood water heater tank is constructed of a core of high strength
aluminum. The interior of the tank consists of a 15% thickness of type
7072 aluminum (pure aluminum and zinc) that is fused to the core during
the rolling process.
This material protects the tank from the affects 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."
Also, if an anode rod is used, many times the metal that used for the
threads is incompatible with the aluminum and differential metal
corrosion occurs. The anode rod then becomes frozen in place and is
difficult, if not impossible to remove.
Anode rods are only necessary in glass lined tanks.

Use them if you like but if you do don't try to get warrentee service from Atwood as it wil be denieded
