I just did a "better-late-than-never "check on the HWS in my 7y.o Jayco poptop. I've owned it for 2 years but never thought to check it. Wow! It started life as a 10 inch x 1" dia rod of magnesium. There was NOTHING left of it and the tank was full of while mineral salt deposits and looked like hell.
As a side issue, I have also noticed that my domestic HWS has a similar anode. Before I start trying to pull that one out I thought I might check with anyone else who has any knowledge of these things.

Hi Peter apart from all the issues that come with a non existent anode, something that you might like to keep in mind is that for some years caravan manufacturers have been installing a tempering valve into the hot water line which mixes some cold with the hot water to reduce the temperature to a level which won't burn you or children. The white alloy salts that remain as a result of the anode doing it's job can and do often block the mesh screens on the hot water inlet to the tempering valve resulting in just luke warm hot water. If it does happen you need to remove and clean the mess filter and flush all the white gunk out of the hot water system.
I have had anodes disappear in just one year, particularly when travelling through SA.
