    Clean, replace, ignore?
    Looks bad for a 2 year old camper I think.

    Might as well replace it.

    It's out. Replace it. It's about to fail at the plug.

    Not really. There's a non-sacrificial shank running down the middle that is totally in tact. This is about how one of those will look after a couple of years. It still has plenty of material left for one more season. It may look like it's about to fall off, but only in the same way that a corndog looks like it's going to fall off the stick, because the stick is such a narrow diameter relative to the meat/breadding.

    These seem to be pretty universal, and I can get 2 on Amazon for $15.
    So I'll just replace it next Spring.

    I thought that would be the thing to do, but advice about something I don't know much about is always appreciated.

    I would have thought that these would last more than a couple years.
    But I'm not sure the old truck camper I had even had an anode in the heater.

    I knew a lot less about this stuff then.

    Not all of them have an anode. Atwood with an aluminum tank do not.

    Dometics do not have anode rods either, aluminum tank, Suburban's use a steel tank. There are 2 types of anode rods, One had a raised place on the end and the other is smooth. Two different materials. If I remember correctly you are supposed to alternate between the rods.

    It is entirely dependent on how many hours of service, not so much years. Having said that they are pretty cheap and easy to replace.

    Suburbans have a porcelain lined steel tank. I have seen after market anodes for the Atwood units. When I install water heaters (or replace) I use the same brand as was in the unit or the one based on the size of the hole that means less work.

    That rod looks fine for at least another year. Mine get changed about every 3 yrs or so, depending on how much use I've given it.

    I think mine looked worse than that after one season! They are cheap enough so I figure I will install a new one each spring.
