2nd AC Wiring
When I add my second AC Unit, my current 5th Wheel only has one unit. Will both units run on 30 amp or 50 amp only? Can you run just one unit on 30 amp and when connected t 50 amp both AC units ...

Dog Trainer,
The answer is a definite "some times".
The risk of running two units on 30 amps is low voltage. My comfort zone is 107 and above. Below that threshold, I either lower the load, or use other strategies.
It behooves you to monitor voltage when running 2 a.c. units on 30 amps.
There is more than one possible solution.
You could add an autoformer to support the voltage. This is my preferred solution.
You may be able to use a hybrid inverter/charger with load support. You may have to "force" the inverter/charger from load support to voltage support. They are not designed to support voltage, but rather to take care of short time over loads--such as running a microwave to heat up a cup of coffee.
