20 Amp Circuit to Support 2nd A/C Unit
I'm pretty sure one of you have already done this the easiest way, so no need for me to reinvent the wheel, right? My trailer is a 30 amp system, so I believe the easiest/cheapest method is to add ...

The thing I like about using the 20 amp feed from the pedestal to the 2nd a/c unit is that you have the 20 amp pedestal breaker protecting the line there. If you feed this from the 50-30-30 dogbone, the only breaker between source and 2nd a/c unit is 50 amps and that's not enough to protect the a/c unit. The other 30amp leg is protected by the power center in the RV.
One other thing I didn't attempt to address is the protection from the 30 amp hard wired surge guard now in the trailer. This will do nothing to protect the 20 amp 2nd a/c unit circuit. And unless I purchase an additional protector, it will remain that way. I do have a TRC digital line monitor that will alert me audibly if I have low voltage and will know if the hard wired surge protector cuts off power to the rest of the trailer.
