    Onan Fuel Usage?

    Headed out next week on our first trip boondocking with our new 350M. Looking for an estimate on fuel useage for an Onan 5500. I don't want to end up with a lot of gas in the tank after the trip. We won't be running an air conditioner, just charging up the batteries each day and probably a little TV in the evenings. I know there are a lot of variables, but an estimate on hours of useage per gallon would be appreciated. Hopefully it is not "gallons" per hour. Thoughts appreciated. Thanks!

    Concensus is about 0.6 gallon per hour at half load and 0.9 gallon at full load.

    I agree, that's almost exactly what I get.
