    well after finally catching up for the hurricane and recovering from my other job of working so many days straight with hardly any sleep, i can tell you the verdict. 8 mpg with my sierra and that's a mixture of city and highway. im looking at a 6.0 now. 2006 f250 king ranch. only thing that worries me is that its was sold in jan of 06 so its one of the earlier 6.0s which had more known proabs then the late 06 6.0s. according to car fax, its never had the heads done, just other minor stuff. its has 50k on the dash. and then reading the 6.0 vs 6.4 on the various forum sites out there. its the same mixed reviews. some say theve never had proabs some say its been nothing but a headache and some say yeah its been a decent truck lol. so i guess its just luck of the draw and what you want. 6.4 gets worse gas mileage, sounds like a danm truck until you roll the window down and accelerate. 250s with the 6.0 looks bad ass and so do the trucks with the 6.4 in them. the new 2012 trucks with the new 6.7 for one sound like complete s^^^ and look like complete s^^^. my dads got the 08 f250 with the 6.4 and only have the radiator hose break (known issue) and something in the steering colum with wiring go bad. hes got 56k on the dash. so i mean, its luck of the draw but isnt it with any vehicle lol. one person will tell you they wouldnt touch it with your dick and some will till you thell touch it with theirs lol.

    and then the other things is, they sell the egr delete which is one of the real bigger issues then the heads on the 6.0 and that will supposedly fix all the issues. supposedly that's the root of 95% of the issues with the 6.0. that and people tune them with chips and do it wrong and it over works the engine which ends blowing the heads.

    i think the fact that ford puts the cummins only in their f650 and up dosent make any sense. i wish they put them in all their units. i love the sound the 5.9. best sounding diesel out there.

    If you are handy with tools, you can fix anything on a 6.0. EGR delete is simple, and tuning has come a long way in the last 2 years. I had an 05 with tunes only, which turned off the EGR...I NEVER had any issues with it and it ran 13.9 in the 1/4 mile; CCSB 4x4 at 8k pounds. As for towing the trailer, I didnt even feel it back there.

    If you need any help with anything ford diesel, let me know. I have alot of experience with 7.3's and 6.0's.

    If you didn't have head studs and never blew an HG or warped a head your lucky. It's usually not a matter of if it will happen but when. Increasing the power just puts more strain on the HG.

    Well just an update, I purchased an 06 f250 with the 6.0. Went from atlanta to new orleans in one tank of gas. got 16.5 mpg on the highway. Its all stock. With my sierra, i filled up 3 times and got 18 mpg. Not much better. I plan on doing exhaust, gauges egr delete and a tune and i should be able to get that number up to 20 on the highway. pulling my trailer is a breeze, i dont even feel it behind me.

    Im in the same boat on this topic. Trailer loaded weights like 4k pounds and my 06 F150 only gets like 9 mpg. Can go 240 something miles on a 27 gal tank! Really breaks the bank when you are filling up your tank every other day.
