Worse than that.

Don't even think of of doing that. Some electrical fixtures are out of your control. What happens when your water heater and converter (battery charger) kick on at the same time? Or the air conditioner?

Would the family be happy if it were 100 degrees and they had to turn off the A/C before they took a shower or washed dishes? How often would they forget?

Be reasonable. Propane is not that expensive, around $12-14 at Costco for a 30 lb. cylinder that lasts all summer. And it's not fixed fee. They meter the fill and only charge for what you get, so filling every time you've camped a couple of weeks won't break the bank.

At the campground where our Cherokee 38P is sited, electricity is measured and it's much cheaper to use propane.

Not "easier"

Not easier. Recovery time on propane is maybe 20 minutes. Recovery time with a 1440 watt or 1500 watt electric heater is an hour. The Camco kit is only 425 watts. Would your family put up with 2-3 hours between showers?

Those that have tried these generally believe they are a bad compromise.

OP - check the back side of the water heater for a threaded hub for the electric element. My Atwood in a SOB has the electric portion on the back side by the inlet and outlet piping. The hub for the electric element may be present even if the water heater is not electric and propane. It may be possible to add the electric components as that system is basically totally separate from the propane portion. A quick check of the Atwood/Dometic website has info showing what I have described.

If your R/V is only a 30a service, I would NEVER want any one single appliance to consume every amp of electricity that I have coming into my power distribution box from the pedestal.

If ANYTHING would be on when the on-demand water heater kicked in... SNAP... there goes the breaker!

Even on a 50a R/V service you'd have to have it isolated to one side with few other things on that side of the buss.

dmctlc mentioned having an Truma electric on demand in their Class A... maybe they would chime in with the model and the amps it draws. It might be a better choice.

Keep it Simple

I just added the Camco electric anode to my gas heater and we just camped and I never turned my gas on until I knew high demand was coming up. When I added the Temp. rod I had to make a sealed hole to the right of the tank cover close to the door. I never had to touch the gas line nor did I want to. I had plenty to line to mount my switch under the counter. Let me know if you need photos or you have it covered.
