I have almost 30K on mine as well. I just took it to the ford dealer for a service bulletin where they reflashed it and replaced a radiator hose coupling and it gets about 2 mpg better now.

I haven't had mine reflashed yet, to my knowledge anyway, but I have to take it in for a service bulletin thing so maybe I'll have it reflashed then.

I am at 13.4 mpg...90% city driving..had 1 flash, truck runs excellent. 25k miles and the more I drive it the mpg keep getting better.

Saw a 6 door F450 going down the road yesterday. Looked VERY Sweet

2 radiators, towed off the freeway twice, high pressure fuel pump, engine electrical short, rear main oil leak, current oil leak....buy the extended warrenty..you will need it. 08 F450 fuel pig

I have a 08 F-450 King Ranch with only 12k miles and no problems so far. The only thing is the MPG is terrible. city is around 10, highway 12 other than that its a GREAT truck.....

This is directed to Jassman, what rear end gear is your truck? robertjr

Thanks for all the responses guys. What started me looking at new rigs was we recently towed my Cig with a buddies '06 F350 SRW 4X4 6.0. I was thoroughly impressed with the ride and towing. Even got around 17.5 mpg coming home without the boat (according to the trip computer. Probably was a little worse than that).

I've heard reports all over the spectrum about the 6.4's from love to hate. Just makes me a tad nervous when the info is about 50/50 good to bad. Even some of the die-hard Ford people aren't really ecstatic about the new motor.

08' F450 with 4:88 gets about 8-9 mpg with 52K miles.
Replace the front diff, transfer case, radiator, Fuel pump twice. Been standed and towed at lest 4 times with boat, wide load, not fun.
Its for sale!!!!!!!!!!!!!!

Don, go buy a clean used '07 with a 6.0 if you're worried about the new motor. Probably get one for half of what a new truck would cost. Thats the way I would go if I was in the market right now.
