I will check the power on the RV, just and assumption but wouldn't the manufacturer spread the current out evenly on a camper that is prewired for 50amp service... I know what assume means. :)

You would like to think that wouldn’t you? I think most are on separate hots but you would not be the first to report them both on the same hot.

Interesting discussion. I still don't see why there is any need to balance. A 50A leg can easily handle 2 AC's even if something like a water heater is running. All three of those running at the same time would still be less than 5000 running watts - well below the 6000 avail. The RV's panel doesn't care - you could max out one leg and have nothing on the other leg without any heat, etc.
How about those large class A's out there with 3 and even 4 AC's purring along in Las Vegas? Do they never run three or 4 at once? It sure sounds like they do when you walk past them..

If I'm missing something, I'd enjoy learning.


EDIT: found this old thread that suggests running three at once (so 2 on one leg) is no problem: Linkaroonie

Although I tend to agree on some Ways my particular case is different, and it may be for some others as well. My truck is a Powerboost, it’s a Hebrides F150 that uses the electric motor to charge up a 1.5KWhr battery, then an inverter. Inverts the signal into 2 3600watt legs. So my generator is 7.2KW on the truck but output is limited to 2X 3600watts. If the two AC are on the same leg I most certainly won’t be able to run both at the same time. A simple rewire to have them on different legs would definitely make sense in my situation.
That being said I can not possibly think of very many situations that I would need 2 AC while boondocking. If I have a power failure and move into the RV for a bit, maybe, but that’s doubtful as well because I wouuohook the truck directly to power my house.
My goal is to find out all the possible solutions, research them all and then make the decision that will work best for me.
I do appreciate everyone’s insight. I’ve learned a lot with all your help already.
