Generator Question -- gph on 5K Kohler?

[pullin]

I have a 2000 270DA with the 5K Kohler generator. Does anyone know a rough average of the fuel usage when it's running? I realize it changes with load, but assume just the A/C and one TV/DVD are being supplied.

Thanks in advance, I don't have a fuel flow gauge or other way of determining the fuel usage while I'm out for a weekend.

I don't have any validation, but was told 1/gph is an average amount.
