The new EU3000I handi weighs right at 80 lbs. It fits perfectly (and semi-permanently) in the bed of the truck. I don't plan on taking it out of the truck bed all that often. Gosh, there are so many viewpoints on the generator situation. Both Honda and Yamaha ADVERTISE the use of these small generators for RV use specifically for running the 13,500 BTU A/C. Virtually every RV forum also extolls the virtue and long service these generators provide. If they are that unsatisfactory and "burn out" due to being used in heavy service to run all these air conditioners, there are thousands of us who have been duped. I also think the manufacturers could easily be held for false advertising since they sell these generators for the exact purpose for which we are using them. My opinion.
The OP has a 15,000 btu A/C which draws more current than the 13,500 btu

I have an old Armstrong that doesn't have a soft start capacitor on it (yet) a pair of Honda 2000's struggle to get it started on a hot day with the old uni-volt running too. A 3500 can't do it. I have a long history with both Yamaha and Honda generators in the construction business. Honda has always been my first choice. Yamaha had a problem about 18-20 years ago with longevity of their engines and oil consumption. Honda has been consistently dependable. Currently either one is good and Yamaha has been upgrading small things to make their units more convenient to use, Honda not so much. Both are quality units and with reasonable care will last quite a while. I have two construction grade Honda units on my farm, one is pushing 20 years old and has over 4,000 hours on the meter, still starts on the first or second pull. It gets run once a week on average.

When we boondock we link two Honda 2000s together and they run our 15btu A/C just fine; however.....if the A/C is running and the water heater and microwave fire at the same time the breaker will kick off the A/C. We try to remember to turn off the A/C when firing the microwave.

That same thing will happen if you are plugged into 30 amp shore power.

Long term or short term? Make that hours versus days. A 15k unit may work well with a pair of 2k Hondas, but what of constant extended use?

Asked rhetorically in this thread, that would be the question to ask and answer reading other threads, IMO.

The same thing will happen if you link 2 Honda 3000s together.

Boat motors and generators are designed to operate wide open for extended periods.

With the RV AC's you have the fan motor as well as the compressor trying to start at the same time.
Not necessarily. If it's hot enough for me to be using my AC, I leave the fan set to ON so the genset is not having to power up both at the same time.

My '13 EB with a 15k AC, the fan starts first then 10 seconds later the compressor starts.
On shore power I have tried the AC + micro, no issues with breakers. The refer, 12v converter, and water heater were also 120v powered but I can't say if they all were actually drawing power to operate collectively.
This is the first I have seen reports on the 2K genny pairs running a 15K unit. I figured 30 amps is 30 amps and cutting power to the refer and water heater would give me some amps slack to run the AC.
I have had a Yamaha 2K now for a year, it will run the water heater and the converter barely during my load testing. The TV, sat box, converter, possibly (can't remember) the refer, will run in eco mode easily.

I have recently learned that Cummins makes a generator that can be installed in an Airstream. In fact, there is a RV dealer in my area that is recommended by Cummins to do the installation. I will talk to them later today or tomorrow but was wondering if there is any one out there that has done this, and if so what has been your experience. They are specifically recommending the Cummins 4.0KY-6747.

I have a Mitsubishi A/C system in my home that has a VFD variable frequency drive that allows for lower power starts on the compressor, I've also seen VFD's on boats during my time in the Coast Guard. Now I see that Dometic makes a VFD of sorts called the "Smart Start" on it's marine app. A/C units. I don't understand why Dometic and Airstream don't get together and add this to the RV A/C line?

My fan starts...then about 5 seconds later the compressor starts.

Hi B. Goldberg"

You will find there is a very big difference in size and weight when you go from Honda 2000 to 3000 or bigger. This is why a lot of folks suggest using two of the Honda 2000 units together. They work in tandem and can do the job you are trying to do.

There are several ways you can do what you want. A big heavy genset, two smaller ones, or only have A/C when on shore power, etc.

Since I intend to run primarily off inverter power most of the time and want enough storage to do that, I have 220 aH of AGM batteries and will buy a good inverter charger to work with them. I already have the Honda 2000 and have no wish to deal with anything heavier. So, I have been looking for a way to get the Honda 2000 over the hump on running the A/C without having to carry any extra equipment to do it.

It is starting look like this can be done with a "generator helper" inverter. These are available from both Xantrex and Magnum. It is a setup popular in the marine community. The inverter supplements the current in response to demand, for example when the compressor kicks in. Some can put out as much as 5kW. When the A/C goes to fan mode, the Honda can catch up and actually be charging the batteries until the need for big juice to start the compressor again.

Good luck,

Andrew
