I didn't get a chance to look at my heater today but was told I would see the hex head once I remove the cover. The anode appears to be about 6-8 inches long according to what they showed me. What do you think?

My 2015 Challenger has no anode rod and I verified that with the dealer during the PDI when he showed me where they stored the plastic plug after winterizing the unit. When I look at the configuration of the water heater I can not see any way to install an anode if I wanted to because of the location and angle of the drain plug hole. Also, the operators manual for my Attwood 6 gal water heater makes no mention of an anode rod.
One recommendation I will make is to always use a 6 point socket or box end wrench when removing or installing the plug. the use of a 12 point could round the end of the plug if that wrench or socket is worn or if it is not positioned correctly (angled on the plug end) for removal and/or reinstallation.
One additional point is that on my prior coach I had a Suburban hot water heater and it did have an anode rod. In that case, and I'm not sure about all cases, the anode rod and drain plug were one in the same. You had to remove the anode to drain the hot water heater. The general rule of thumb, and recommended in the that Suburban owners manual, was to replace the anode rod after draining the tank for winterization.
