I looked hard at the yamaha, honda, and Kipor. The Kipor is by far the least expensive solution. The yamaha that will power an A/C is $2400. Two Honda 2000's is almost that much once you buy the parallel kit... or you could get the 3000i. The Kipor I have is the KGE3500ti. (it is now the 3000ti) It is VERY quiet. I have had two honda owners tell me it is quieter than thier 2000i's. Also, it does have a 30AMP plug. It has electric start, and a smart throttle, that throttles down when full load isnt needed. It will power my A/C, but it can't have lots of other stuff going when the A/C kicks on. Other than that, it is as Wayne says, it will run everything no problem. I might even know where you can pick up one that has only been used twice. A friend of mine got one for his toy hauler, then ended up buying a Four Winds Fun Mover, that had a 4K watt Onan on board. If he hasnt sold it yet, I bet you could pick it up for a few hundred less than new.
