real world mileage?

I was getting 14 on a real good day with a stock 350, a 6" lift, 35's, and OD.

on the highway i can get up to 16.

on a bad day i got around 10.
 
My 99 Yukon with a 5.7 only averages around 12mpg. I have seen as high as 16mpg and as low as 10mpg.
 
My 95 4 door Yukon with non Vortec 350 gets a consistently bad 12 mpg with Goodyear MT/R's and a very light right foot.
