I have to find out why they don't recommend one.

FW,
Something I found
Another way of obtaining cathodic protection is to connect the aluminium object to the negative pole of an exterior DC voltage source.
The first way the article discusses is the use of an anode rod.
The way I understand the info above is that the direct grounding of the Attwood tank to the DC side of the coach would serve the same purpose as an anode rod in an aluminum water heater.
I haven't looked at my Attwood water heater's schematic but I wonder if the tank itself is grounded to the vehicle chassis or in some manner through the house batteries using some type of lug or jumper.
