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 ...

Lowes has some very small breaker boxes that can be used to protect your aux line. If you're hankering for 30A you can feed it to a small box and then break out two 20A's internally. As said, there are (very expensive) adapters to go from 50A to double 30A, but IMO you'll still get the most mileage out of 20A aux service.
30A or 20A, IMO the real value of the aux is that a portable gennie or low-capacity source can be ADDED to your shore source (or internal gennie)
I understand. I hadn't thought about powering the 2nd a/c with a genny. My trailer has an onboard 3600 watt Onan LPG Genny, main air is 13.5K and I plan to add a 9.6K 2nd unit . Could probably power the 9.6 with my Homda if not too high in altitude. Good info.
