I have a 1999 2500 with the 6.0, I get about 12-17 on average, when pulling my 5th wheel (about 11k lbs) it drops to like 6 mpg

My 05 got 10-12 around town, 16 on highway @ 55-60 and 13-14 @ 65+. I drove pretty gently around town, if I was in a hurry it didn't seem to change much. The highway speeds I listed are with cruise set. Towing 2000 lbs @ 70 mph it dropped to a steady 10. There is almost zero flat ground where I live so take that into consideration.

I have a 01 2500 with the 6.0. Around town and I live in a pretty busy area I get about 10. When I’m driving highway I get between 14 and 18.
