I picked up the new 179.  I got into a discussion with the parts guy about what generator is needed to run the A/C.  He's saying minimum 3000 watts and wants to sell me 2 2000 watt units.  Yamaha, and several people on this forum say the Yamaha 2400 will work.  I would like to hear from people with this unit if it has damaged their A/C as the dealer said it would.

I used a Yamaha EF2400is with my pod for a year w/o any problems.  Others here use them, too.  You must turn the A/C of temporarily if you use the microwave but that's it.

What Doug said.  I have a Yamaha EF2400iSHC, and it runs the AC fine. Two 2000s would give you plenty of power and the flexibility to haul just one unit sometimes.  The rest of the time it would force you to haul two generators around.  I'd rather go with one 3000w generator if I felt the need for more than 2400 watts, but I don't feel the need.

Something else to consider is altitude.  Granted, if you are at 7000 feet you probably won't need A/C, but the higher you go (and the warmer the air is) the less power you get from an engine.  My current genset, a Honda EU3000is will run my A/C and microwave together at low altitude but it choked this past summer once we got up high.  If you regularly run at high altitudes you should change out the jet in the carb, which may help with the power problem somewhat since you'll be back to an optimum air/fuel mixture.
 
I never ran my Yamaha very high when I had it (most of our trip that year was along the Gulf coast and plain states) so maybe someone else here can confirm its performance at higher altitudes.

I'm about to find out on our trip as our first multi-day stay after arrival in Colorado will be at 9200 ft.   I went through quite a bit of trouble finding correct jets for the 2400isHC. 

So I ordered about $25 worth of jets (3ea) from a jet specialist place, turned out they were all the wrong physical size even though the metering hole is correct, and can't be returned.
The carb is a small Mikuni but small Mikuni jets aren't the right ones!
Called Yamaha and they gave me the specs and part number for the jet at 6500 ft.  They also have a jet for 9500 ft but say it isn't available in the US!   I guess they don't realize we do have mountains higher than that.
So I gave in and paid $10 for a genuine Yamaha 6500 ft sized jet.
Then after getting the right jet in hand and doing a lot of digging I found a place that stocks the correct physical size Mikuni jets, but the metering sizes Yamaha uses are custom and don't exist in the aftermarket world and you can only get close.
I've done a lot of jetting in my dirt bike days and already had a number of Mikuni and Keihin jets on hand, but of course none were the right ones.   One thing to keep in mind when jetting- if you can only get close always go on the rich side, too lean can damage the engine.

I assume that would mean if you've re-jetted for 6500 feet, you shouldn't run down the mountain to the beach and fire it up because it would then be too lean?  That would be an argument for keeping the sea-level jet on a long trip where the altitude will vary a lot, and just deal with the altitude derating.  For instance on my recent trip I ran mine anywhere from 1000 feet to over 8000 feet.

Yes that is correct- if jetted for high altitude it would be too lean at sea level.
Old school Onan 4kW generator in my toy hauler- has a knob you turn to set mixture that is marked in altitude.  New school invertor generators- NOPEConfused

I can change the jet in my Yamaha in about 15 minutes, maybe quicker.  
Design flaw they built in-   again does anyone actually field test these things before they release them for sale?- 
 there is an obstruction that blocks getting the fuel bowl off the carb to access the jet- another 3/8" thickness in carb insulator would save taking 2 nuts off and sliding the carb out on the manifold studs to get the bowl off.  
Someone's CAD program missed that and apparently no one in testing actually tried to change a jet..Ouch

Seen that many times on cars/trucks.  Regular maintenance items like spark plugs where 3 of them are a 2 minute job, total, but the 4th is a 20 minute adventure only by feel (back when you had to replace them regularly and not 100k+ miles).  Clips for the air filter cover that are impossible to unlatch.  Covers for lights bulbs (well before long-lasting LEDs) that require major disassembly even though it takes 3 seconds to change the actual bulb.  I've seen badly designed user controls too, stuff that really matters to every Joe Smith and not just his mechanic.
But I've seen the opposite, too.  Cartridge style oil filters that are front and center when you lift the hood, and don't need torquing down, etc.  Good user interfaces, too.

The only slight issue I've experienced with running our Pod with the Yamaha 2400iSHC is that I need to turn on the fan first before setting it to cool (turning on the compressor). When the compressor starts, the fan stops briefly, less than a second. Other than that, it works like a champ.

I bought the Boliy Pro3600Si generator and it was able to power the A/C no problem. I did an extensive research on reviews about this generator. Price, weight and dB rating are what attracted me to it. I haven't used it much so I can't really comment on the longevity. But it started on first pull and pretty quiet, especially on economy mode.
