just finished a 2588 mile trip pulling about 12000 lbs. (5th wheel)DW kept track and here is the low 9.4 and high 11.9-2013 Dodge 3500 4x4 with 6 speed stick-truck did a very good job-I was impressed!...
That mpg sounds good to me . I only have 520 # of torque. If I had 765 # of torque I would use it . I already tow too fast . So my mpg would suffer , anyway . Thank you for the info .
