I have not seen any change in operation using the boiler for hot water and heat, just hot water using only one AC circuit. When the coach was new during normal summer months one AC circuit on would cover normal hot water usage. Now it does not. May argue against glycol fluid as the issue.Glycol based heat transfer fluids (aka: boiler fluid) do deteriorate over time. I did a google search, and every result was a paywall, but the cache data suggested 3-5 years was the typical useful life.
Yes, that would argue against boiler fluid.I have not seen any change in operation using the boiler for hot water and heat, just hot water using only one AC circuit.

I have not opened the cover yet but did check the amp draw previously. Both elements are drawing the same amps as they did when new. Time to pull the cover.Yes, that would argue against boiler fluid.
Another test point would be amp draw. Pay attention to the AMP load before you turn on the burner, and then see how it changes with 1 burner then 2.
A shorted or bad heating element will be "open", and therefore amp load will not increase. Same will be true if the wire became disconnected (aka: burned up).
A properly running electric heating element will be 10-13 amps of usage. Test with 1 element, and then test with 2. Make sure each climb up in usage.
**BEFORE DOING THE FOLLOWING - TURN OF ALL AC & DC POWER TO THE COACH**
For more detailed testing, open the cover and expose the electrical ends of the heating elements. Disconnect both wires so there is no circuit to the heating element. Then with a multimeter test the resistance between the 2 connectors. Properly working should be in the range of 10-30 ohms.
