I have the dual (gas/electric) water heater on my 2017 Georgetown.
Last year, the propane side of the heater was inop. No spark, no gas (I presume). The electric works, but it is not as hot.
When we returned home, it began working. I touched everything that I could and found no problems.
This spring, we went to Texas, no propane hot water. Back home, I again went searching...cleaned the igniters, made sure that the propane path was clear, found no issues and BAM, it began to work.
Here we are in Tennessee and we have electrically heated water only.

I'm out of ideas.
 
Sounds like a wonky regulator. Do other gas appliances work?

Yes. The stove, outdoor port, and furnace are fine
Sounds like we've narrowed it to the water heater. It's either not getting gas or not enough gas. Does it have a pilot or electronic ignition?

Maybe trace the feed line back to the tank to see if it's pinched/kinked anywhere.

So! Stand out by the heater while someone else starts the heater, and tell us what you hear! And oh yes, did you check battery voltage?

Nothing and 13.4
Since it has worked intermittently, a faulty igniter has been suggested.

Standing next to it you can hear the solenoid click in. No click, no gas!!!

You will next hear the snapping of the spark, no snapping,no spark!!!

First, because it is intermittent, I would be cleaning All contacts. Due to your messing with things,then finding it works for a little, contacts on the low voltage side are my diagnosis.
