fuel economy for 2004 avearage

[RobertSimmons]

I have 5000 mi. on new truck. 600 HO,4x4,3. 73gear w/48re trans.

currently getting 12mpg towing 5000lb trailer and 15 empty on highway.

is this aveage or not for others of you with same setup?

Might get better exposure in the 3rd Gen forum. Lots of MPG threads there.
