I have the Honda 1000 inverter which I use for my boat (lund fury) and a Yamaha 2400 which I use for our 34 ft. hemisphere. We go primitive camping often in the north woods of Wisconsin. Honda and Yamaha are top of the line, flip a coin,, it comes down to the spec's ie. weight, dimensions, gas tank, fuel shut off etc. to which one you will choose. Nothing is as quiet the Honda or Yamaha, Honda 3000isu is the lowest dba. The Champion 2000 & 3000 are the best in their range, but remember its hard to find a local dealer for repairs and parts. If your not doing 60 percent of your camping in the primitive,,, you'll be alright with Champion. PS the 2400 Yamaha will not run my 15000 btu, it did run the 13500 but I don't need a/c around Lake Superior.
