I agree with Frank. The threads on the anode can get very rusty, even with teflon tape. I replaced the water heater in our last 5er...wasn't a bad job. All you can do is muscle it out and hope for the best. Or just use it as is until it doesn't work anymore and replace it then.

If you can't remove the anode and the heater does eventually fail you will want to drill a hole near the anode to drain the water before removing it from the trailer to avoid excess water inside when disconnecting.
