First tow, kinda disappointed.

Add the Edge EZ you will be happy after that

I did my 1st long tow this past weekend with my 04, weighting in at 16,000 lbs (truck and trailer) I got 13mpg and that was doing 55-65 mph. I found I had more than enough power out of the 5. 9 but I also have the Edge chip, as well as other mods (see below).

The best I ever get empty is 19 mpg.

But hey I once almost got 25 mpg ! but shucks it got away
