15 mpg 3500 4x4 5spd 4.11 is that it? 97 200k

I posted about a year ago stating that no matter how I drive, hard, easy slow, fast I got 15 mpg, no better, no worse. when I tow 16k behind me I get 13+ mpg.

from what I have read I figured to get 17 mpg. had a 350 5spd 3.5 2wd that got 22 so it was a bit of a shock to see such low numbers.

I have added the following mods 10 plate and 3gsk. did not affect milage.

The only thing i have not done is check timing. the cost of the tools makes the payback if it is slipped a hard call. So is this 15 mpg in the ball park?
