txgencon, mind me asking what you got out of each under normal loaded conditions?
txgencon said:Empty, I could get 22-23 mpg with the 6.0 and 24-25 mpg with the 4.8 if I really took it easy (highway). This was on the level terrain in my area. I drove the 6.0 very lightly loaded to Red River, NM (from Dallas) and pushed it a bit and got 17-18 on the overall trip (mountain terrain when we got into New Mexico). On the long haul (Dallas to Amarillo) I drove the speed limit (mostly) and used the cruise control. I actually got a warning ticket coming back for going 79 mph in a 75 mph zone. State trooper said, "You gotta draw the line somewhere."
thats a lot better than the trucks with a 6.0, that was my experience. Surprised the vans do so well!!

Do you drive down hill both ways?? Both my 6.0's get 12. 13 if I'm really lucky on highway. They are both 1 ton vans. 04 and a 06.

I would deffinetly not get the 4.8 for that size truck. I had my truck weighed, with my normal load of tools its 8800lbs. Once I hook up a trailer its deffinetly lugging up the hills. I will be doing a gear swap to 4:11 gears as soon as the weather gets a little nicer. Dave
