Yes, I am using the cord from Honda and I am using the correct cords in the correct places L and R, right being red and so forth and yes, I I am using the 30 cord from the front of the trailer into the Honda 2000 Generator.
Thanks for contributing and if you have any other suggestions, I would love to hear them.

The batteries on the trailer are brand new, and the trailer has barely been used. We are not at high altitude.

Did you put oil in (or check the level) the generators?

Try doing a load test where you have a couple of space heaters on high. If they can't handle that much load then they won't be able to run an AC unit. It should not be connected to the trailer to do this load test.

Make sure the gas caps on both generators are turned to "on"...this allows air into the system so the genny can draw fuel. If they are in the "off" position, they will run for a while, then falter and stop. I have forgotten to switch them to "on" more than once!

I've had my generator (Yamaha 2400) fail a few times if I wasn't careful to switch the refrigerator and water heater to gas. The surging could be a problem with that generator or additional loads being put on the generator. I've been told all Dometic Penguin II a/c's have the hard start kit already installed - it is a capacitor designed to spread out the high current draw when the a/c compressor starts to avoid overloading the circuit.

For the person who asked about the Univolt.. It is generic term now for the power supply/battery charger that the 110 volt power goes to first, inside the trailer. It draws electrical current "off the top" of the incoming supply to charge batteries (Priority 1!) and then provide 12V power to inside lamps, fans, refrigerator controller, furnace and water heater control circuits and valves, etc.. Whatever is leftover is available for the Air Conditioner or Wall Outlets or microwave in the trailer.. Most trailers are wired so the air conditioner and microwave can't be tuned on or active at the same time (those plus residual current load of univolt/converter exceed 30 Amps..).

If generators are surging and revving up and down, then I'd suspect one or both generators, or the bridging cable/hookup. When our Honda 2000 capacity is exceeded, it just tries to rev a little and shuts down. Using the Eco setting does cause a lot more speed variations with lighter loads, but should stabilize.. We also discovered that carb jets do get clogged if units have sat a while with gas in them, and it takes 15 or 20 minutes of running to clear all of the carb jets.. We've not had good luck with Stabil or other alleged gas stabilizers, though I realize that is a different thread altogether...

Yep, this would cause the generators to shut down. I've done this before too. I suppose it's possible that even if turned to "on". It may not be venting properly. One more thing to check.

Does your trailer have an electric water heater option?

If so, it is a heavy electrical load.

Regards,

JD

Did both units rev when ac kicked on or tried?Are both units showing overload or just one?

I have a 15000 btu ac unit and the same gens that you have,I start my gens then go to thermostat and turn on ac it usually takes 2-3 mins the gens ramp up for 3-5 seconds and then the ac comes on and gens rpms fall back down

.Eco mode only works for charging Batteries or light load.
It sounds like you are in eco mode

Smile ANSWERED by Honda - Other things trying to come on!

I spoke to Honda to get help and they said to make sure ALL things are turned to propane gas or off.
He explained that as soon as the trailer has power coming to it, it attempts to start heating the water in the hot water heater, and it starts to run the refrigerator that could either be on electric or auto, or gas.
He said to double check that all are set to propane or off.
After checking, our little button switch in the bathroom was in the "on" position and not off for water so I turned it off.

I now have a perfectly running AC unit running in my airstream and I am ready for my next trip!

Thanks to you all for your help.
I hope this helps another RVer who is having the same problem.

For sure, this will get you. I am still having the main 2000 Honda not run smoothly, and when I asked the guy at Honda, he said, it can "look" for a load. Not sure about that, but it would be nice if it ran as nice as the companion I got with it.

There's your answer.....you need what is also referred to as a "hard start capacitor" installed on the AC unit itself.
Easy to install by an AC tech and the part is not very expensive.

Jonnagyp ... You didn't say, so I just wanted to check to make sure you are connecting your Airstream's shore power cord to the Companion's 30-amp outlet...you do need an adapter for it (which converts the twist & turn female plug on the generator to a regular female 30 amp female plug). Pic below.
