Went to drain the water tank and inspect the anode rod and found it just has a plastic threaded bung and no anode rod. Do you'all have just the plastic bung or do you have anode rod?
No anode in mine but it's an all-aluminum tank. Doesn't require an anode.
Same as bdale, no anode rod, aluminum tank.

I thought that with aluminum tank you wouldn't need one, but wanted to be sure.
Thanks
Correct. With an ATWOOD water heater which Foretravel used, no anode. Replace the Atwood nylon drain plug annually when you service the water heater. About $1 each at any RV store.
Excellent comment.......our's had not been serviced when we got her and I noticed right away the nylon plug had SPLIT and was leaking! :facepalm:
I replaced our plastic plug with a galvanized plug and a petcock in it for draining. Is that a bad thing?? Dissimilar metal ??
Yes, a bad thing. The aluminum tank is now the ANODE and will erode to protect the galvanized steel. Also, the steel threads are a LOT tougher than the much softer aluminum threads of the tank.
K... well it's a good thing I kept the plastic plug. I'll be switching it out tomorrow when the water is cool.
Thanks Brett..
Use a new one. They do age and get brittle.
2 1/2 wraps of teflon tape helps seal it. Start by just a little tighter than hand tight. If it leaks, tighten a little more. Said another way if you crank on it, you can break the nylon plug.
But broken plugs are easy to remove with a sprinkler head remover tool from any box store.
