I tow with an 06 6.0 fx4 lariat crew cab with the 8 foot box, 146k Has EGR, and stock head bolts on it. At 140k the vnt turbo needed cleaned out. Original motor original trans. Change the coolant annually, change the ATF annually, and have kept it dead stock. Its not the horrible motor people who have never owned one will blindly repeat that it is.

Get 13-15mpg pulling a trailer, and seen as high as 20 unloaded. It's been a great truck.

Have another buddy with a dead stock 06 6.0, 150k, original motor original trans original turbo.

05-07 had many improvements over 03-04. Its worth doing research outside a Mercedes forum where very few commenters will have ever owned or worked on one.

Key to the 6.0 seems to be not chipping it. All the guys I've met with "6.0 problems" had a tuner on one. A stock 6.0 will run down a chipped 7.3. Keep it stock, plenty of power.

Its not the weld the hood shut maintenance plan the old 7.3 was but, coming from a 6.6 duramax you ought to be familiar with more modern, more complex diesels.

6.4 has more cab off service and with its DPF they get much lower fuel economy than the 6.0.
