Combined

I only average 13 on 93 with the Whip. RCSB weighs 6k as loaded daily. I don't drive aggressively either unless I need to embarrass some jackass. Mostly city but some highway. Should do better after I get a custom tune.

Double cab 4x4 with a 6.2 and it's a pig...... like 15 combined and I do mostly highway. Unless I want to do 50 mph I may as well drive the old 05 1500HD 6 liter truck.....

I average about 15mpg... that's light traffic in the morning and heavy traffic in the afternoon.
