We took a 100 mile loaded trip this week. I was driving a stock early 1999 F350 6 speed with 4:10 gears. My father was behind me pulling with his new 08 F450 with 4:30 gears. Very similar weight between both trucks. Surprisingly he didn't have that much more power than the one I was driving. As we run the hills he could keep up and on rare occasions he could gain a fraction on me. At most times the 7.3 could hang with him. When we drove empty going back home he couldn't gain an inch on me. I would just wait until he hit 82 mph and then pull up on his rear bumper. Why shut down a new vehicle at 82? Guess they don't think it's safe to tow any faster.
But, the 08 problems are non-existent now. Finally the bugs may be gone. The 7.3 got 12 mpg. That was loaded going down and unloaded coming home. The 08 got a little over 9 mpg doing the same.
Next time I will drive the 03 F450 and blow the 08 away.
A buddy of mine just picked up an 07 F-550 with a dump box. With out a question my F-450 weighs more than his F-550 the way they sit...anywho..long story short we want to race them and see which one is faster
It will be like watching two ice bergs floating down stream

We pulled the cars back home tonight. The 03 450 out front, 08 in the middle and the 99 in the rear. The 03 would pull the 08 from a take-off easily but the 08 would run with it when rolling. It was fun!!
