I have a early 2011 Cruiser 30ES with a Atwood 6 gal. elect/gas water heater. It does not have an anode rod. The 5er I had before had one in the heater but I can't remember the brand. Is it necessary in the Atwood, if so, why didn't it come with one? Should I install one? Does it depend on what material the tank is made of?
Thanks for the info.
