I am looking into buying either a 2010 Ford F-350 Lariat DRW with the 6.4 engine or a 2012 Ford F-350 King Ranch DRW with the 6.7 engine.Both trucks have about 20,000 miles.I can get the 2010 for about $38-39,000 & the 2012 for about $46,000. My question is the 6.7 engine that much better? I have heard the gas mileage is much better on the 6.7? Any other concerns that I should consider between the two trucks?Also the 2012 still has some warranty left! I like that! Any input would be great!!

Without a question get the 2012 Cummins! :BReally I would go for the 2012 6.7! See if you can get a car fax, and service records. The 6.7 is FAR better than the 6.4.

Both trucks were bought and sold back to the original ford dealer where bought new. They both have all service records.

I have no experience with the 6.4. I do have a 2012 6.7.I would go with the 6.7. Great power. Reasonable fuel mileage. Only real complaint I have read about the 6.4 is poor fuel mileage.

All things considered equal I'd go with the 6.7.

I can only state that I have HEARD the 6.4 does not give the best mpg.The 6.7 is a Ford in-house developed engine. The 6.4, like the preceding Ford diesels was developed by International. That's not a bad thing at all, but I think Ford got so much bad press because of the 6.0 that they decided to develop their own diesel engine - thus the scorpion 6.7 came into being.I have a 2013 F350 6.7 and it is simply terrific. I never want to get out of the truck. It gets very good mpg and is super strong.The 6.7 IS that much better. I cannot advise you about the pricing, but there is no question in my mind that I would want the 6.7.* Ford does have an after-market warranty available for various periods of time. Maybe try and work a deal that includes some extra warranty time.Tim

I have driven for a Ford dealer and own a 6.7 (2011). Not a difficult decision. The 6.7 for many reasons. Better engine, Fuel, 6 speed transmission, and a newer vehicle.

My brand new 2013 6.7 wasn't much more than $46k. I think it's over-priced.

It seems a little high to me also but let's not forget he's looking at a King Ranch dually, which was probably the top of the line model for that year.

That's a pretty loaded up truck.

I've had both. Both 4x4 CC duallies. Go with the 6.7. Much better engine and better fuel economy, not to mention more power.

Without a doubt I would go with the 6.7. I had a 6.4 and traded it for a 2011 6.7.
the difference is unreal. I now have a F350 DRW with the 6.7. I needed a lot more capacity. It's amazing how the 6.7 pulls.
