Well I got down to a quarter of a tank of fuel. Computer resting was 13.5 with 512 miles on the odometer, I filled up with fuel, 39.65 gallons to the top of the filler tube and doing the calculation I ended up with 12.91 MPG. I would bet that the dealership did not really fill the tank all the way up but I will be able to see on the next fill up. I would guess the computer and actual math will be closer on my next fill up.
I am still not sure if I made the right choice with the 4.10's or if I should have went with the 3.55's. I drove the truck to work today to get some more miles on it before I tow over the Cascade Mountain Range next Thursday. Boy is that road a piece of crap, rougher than hell two lane road that makes me appreciate my Accord for my daily driver. Truck is definitely built for hauling a heavy load.
Also ordered my 25k Companion Hitch today. Hope I am happy with that decision. Should be able to assemble, install and adjust it on Tuesday.
Looking forward to my first tow trip with it.
Tom Marty
