My dad picked up one of the Honda eu6500 and they are extremely nice. Extremely quite which is important IMHO and very efficient. Also fairly small, and is really an enclosed style which is also nice. Natural gas is not really a smart move out here in California, unless you are on a big ranch and have your own giant propane tank.
Yep, as with most things, analyze and analyze until I zero in on the answer, and the EU6500iS is becoming clearer and clearer, been getting up to speed on all the youtube info tonight.
The EU6500iS seems to have a lot going for it. Small. Quiet. Inverter with clean power which is huge because of my lousy experience with UPS' during Sandy, I'd rather not need to touch any of the UPS' when on generator power. I'll be able to patch right into the circuit breaker box with the Interlock Kit. I probably only really need a few thousand watts anyway, and the natural gas load will be much more manageable with the smaller unit. I won't need to find a spot in the backyard for a permanent whole home unit, nor need a maintenance contract, and won't need to deal with a long trench to run the gas and electric, and all the building inspector stuff. I'll be able to take this all with me if we ever move, and I'll probably save several thousand $, though the EU6500iS unit is actually more expensive then the 14kw Kohler, but again the inverter is something I desire.
My only worry at the moment is the warranty status with the after market Tri-fuel add-on, and also the more I think about this tonight if I go with the local Honda guy (who I like) I'll need to pay sales tax on the $4K for the Honda, but I guess it is what it is.
Tomorrow's another day, and more analyzing.
