6.7 is such a beast!

Nice truck. I have a dually duramax and who cares what people think about what tows the best. They all have their plus and minuses. Never thought I would be a diesel lover till I got one . I will never go gas again even if I towed a John boat

Got the same truck and it gets 13 empty or pulling a 38 ft boat. 2013

You only get 13 mpg in a 2013 6.7L? What gear ratio? I thought they did better than that.

Here is what you NEED. maybe over kill- BUT it sure turns Heads lol

That is a nice ride, wouldn't fit in my garage...

really 13 empty?? Mine is a 2012 but if I keep it low 70's, I can get 19-20. 80 still gets 18mpg on comp read.
I am averaging 17.5 commuting into New Orleans with traffic.
Havent towed boat yet, but cant wait, this thing is zippy!

Towed my 33 to ozarks this past weekend with friends 13 6.7, about 300 miles, you will love it! Averaged 13 mpg with load, way home about 17.5 going close to 80 whole time.

6.7 is an awesome combo. 2013 450 dually pulls my 33 around 13mpg.... If it got 18-19 I'd buy one!

From today!! Boat ran good, best yet with B1 labbed by bblades. 79 degree, 40 humidity, 1 ft chop, 66.3mph. Realized my trim indicators were a lil off, so I matched up the lil rooster tails and squeezed another 1mph out! Oh, just me and 1/2 fuel
