It uses less fuel because it is only 7/10ths the size.
Half the fuel consumption equates to a savings of a gallon every four hours underload.
Thats 75 cents an hour at $3 a gallon... And it's lab results under the best conditions, not real life.
You'd have to run it 5,000 just to recoup the cost, and another 5,000 to see any significant savings.
And
Take that decibel hooie as laboratory and not real life.
Too many ways to change decibels on your current unit to consider 8dB worth a swap.
If you want to do something that is better:
Order the double alternator kit, have it installed along with two extra batteries and as much inverter as you can afford, then just do away with the generator entirely.
My math might be a little off but I don't see the slightest benefit this side of 10,000 hours.
