I made a round trip from Louisiana to Washington DC for a total mileage of 3,316 miles. Total gas used is 407.19 gallons. I ran the generator for a total of 24.6 hours.
I am using .5 gallons per hour for the generator which comes out to 12.3 gallons. 407.19-12.3 = 394.89 gallons. This comes out to 8.39 MPG. After the trip, I just turned to 12,330 miles on the odometer. Hopefully, I still can get another .5 MPG when I reach 15,000 total miles and it will be fully broke in.
I did not pull my toad and I didn't really go in the mountains, but we encountered some good hills. I did nothing to my engine as it is stock from the factory. I drove between 56-60 MPH and acted like I had eggs under my foot. O' my coach weighted at 20,030 lbs when the trip started. I think if I get the Ultra Power, I may even see 9 to 9.5 MPG. That I could live with.........
