If I understand correctly, the 240v JennAir should be able to run off of 50-amp shore power IF the JennAir is using a 2-wire (double hot) feed currently. I can just do the same from the new 50-amp shore power if I'm able to add it, correct? I do understand that none of the 240v appliances will function properly when I'm plugged into shore power using a 50-amp to 30-amp adapter plug, and that I'll have limited amperage available on both legs of the 120v panel with the adapter.

50 amp RV service is 240 volt and 30 amp is 120 so no, you won't be able to run 240 volt appliances on 120 volt service when you're plugged into a 30 amp pole.

A lot of the confusion around 30/50 amp RV service comes from the nomenclature.  Amps measure current, not power.  A better designation would be 3600 watts (30 amp service) and 12,000 watts (50 amp service).  Those numbers more immediately indicate the difference in available power with the two services.

The last thing I would ever want to do is hurt you.
Its the last thing but its still on the list.

Your land line plug should be near the same place (not in the same) as the water supply so to easily reach the power pole and water supply when you are at an RV camp. When you plug into a power pole (after checking polarity and voltage), the power at the pole needs to be off. Plug into the power pole THEN turn on the power at the pole. At least with my bus, you do this, then go inside and flip from generator to land line, and you're done with power coming into the bus. Having a plug in that has to be changed in the cargo bay is, yes simple. But not convenient or safe when it is either wet or raining out-or even when it is dark.
I have a 4 circuit breaker box-2 for generator, 2 for land line with a cut out slider that prevents the possibility of flipping on both sets of breakers at the same time. Easy to make, makes it both safe and dummy proof. Good Luck, TomC
