The mpg at 65 mph loaded 12 MPG
12mpg is pretty much what I get when fully loaded with my Cummins. So that to me is great.
I have noticed that when I pull my trailer a long ways unloaded then load up and drive the same distance back that the MPGs don't really change at all. Weight seems to have little difference. For example....I bought my trailer in Georgia and loaded up my Cobra in Alabama and pulled it all the way to Texas. Cobra + Trailer = 6700lbs. I got 11.4mpg driving pretty much flat land AL to TX.
Then I loaded the trailer with my Cobra and all my HHGs and drove TX to WA. I went across the scales at 25,500lbs so that means my trailer weighed in at 19,000lbs. I ended up getting between 10.9 to 12.5mpg with a final average of 11.6mpg. This is going up and down steep *** hills too. So I have concluded that weight does not mean anything when pulling.....its got to be purely wind resistance. Thats my .02 cents.
