Admittedly without trailer, but I have lots of power. Blows the pants off the chev 350 I used to drive. Not saying I wouldn't like a diesel��but I can't complain about what I have.
So you got 11.5 on the highway without a trailer? That's what I said I am getting so I don't know what your point is?
My reference was to Ram Daddy who was saying he gets 11.5 towing a 7000lb trailer. I find that hard to believe based on my experience.
If I tried to tow that trailer here I would probably be getting about 5 mpg and have the peddle close to the floor most of the time.
