Seems like lots of sensors and logic boards to fail on new units and calcium deposits kill them after a few years. I would think sitting with disuse would lead to quicker oxidation. Sorry for the lack of help but simple wins for me.
I agree that the factory setup is good for all the reasons you mention.
I like the setup I have been using successfully for the past 11 years. I installed a (so called Hardware store) tank-less water heater behind my reefer running on LP gas. I elected to keep the original factory setup (I did replace the original tank with a stainless steel tank in 2003) plumbed so that I can choose between the factory system (electric and engine heated) and the LP gas tank-less unit.
We can make hot water with LP gas, 120 VAC (shore power or Onan)or engine coolant heat. If staying overnight at Walmart or camping without electric we can shower with the tank-less. If at campsite with electric we can use the factory system. I bought a spare tank-less unit in case the original one dies. It was only ~$150 for the units on Ebay, but of course lots of my time installing it.
