Onan 5500 and 2 Air conditioners
I asked if my Generator would pull 2 AC's and was told yes.
Sure enough it doesn't
One is a 15,000 and the other a 13,500.
Is anyone else running this set-up and can they pull both AC's at the same time. I just got the second installed this morning. of course it worked fine at the dealer. Took it home and wanted to see how long it would take to cool it down and tried to run off the generator and it keeps throwing one of the breakers on the generator.
I would like to know if this should work ?

I have two 20amp breakers one for ac1 on the left of the 50amp main and one on the right of the 50amp main for ac2. Hope the dealer used 20amp breaker deadicated to that second air. An if they did make sure they are not on the same side of the 50amp main.

On my 06 Raptor both ACs were wired to the same leg of gen. Once I moved breaker on 2nd AC to other leg of gen it ran both ACs fine.

I think thats my problem. When it kicks off it kicks off both AC's and only one leg of the Gen.
So.....How do I switch it to the other side ?

If you move it over 1 space right or left.. that will do it. you just want to get it on the opposite phase

So I did a little investigating 
With the front AC running I figured out that if I flip the breaker marked W.D it killed it.
With the Main AC running I flipped the breaker marked AC and nothing happened. I flipped breakers until I flipped Mic and it went off.
I would suspect with my no electrical experience that the drunk guy at Keystone wired things up ???
Heres a pic. Do I need to move one ov the AC's to the other side of the main ??? Like maybe where its marked AC ?

Your guess is correct. Left side of the main is one leg, right side of the main is the other leg. For the generator to do both, the A/C's need to be each on one side.

So all I need to do is....
Disconect the power
Pull the cover off the box
pull the breaker
Disconnect the wire from the breaker
then switch it to a breaker on the other side.
Just one wire per breaker ?

OK, yep if you move breakers you should be fine. We have 2 15K ACs and can run them both from our Onan 5.5K Propane Genny.

Pull the power, open up the box, I would pull and swap 2 breakers (usually easier then removing and reattaching wires). Put one ac and micrwave on one side of the main 50 amp, the other ac and converter on the other side.
Remember to turn the electric Water Heater off unless you are on shore power. (Very expensive to heat water off a generator VS propane). If possible out the bathroom outlet of the same side a the Microwave, then either the hairdrier or microwave when on generator power.
I rewired my main ac, electric water heater, and abandoned the converter breaker when I put in my inverter/charger.
