A lot of euro spec tires don't meet our nanny state governments regulations so we don't get in on the fun. You can get them but it is not easy. I did in the past have connections to do so but that has long passed. good luck.
I absolutely agree with EPA and every other nanny state agency ruining diesels and gas rigs alike.
Urea fluid. ...******, really?
Ethanol ruining fuel systems costing millions to the consumer, proven combustible energy loss high prices at pump for crappy fuel etc.....
TO THE OP. If you have some free time, Google Ford/Navistar law suits or 6.0L law suits and do some reading. That will pretty much put to bed the very few boasting how wonderful the 6.0 is (Er...Can Be). Somewhere you can also find TSB's (Technical service bulletin) on each year of vehicle your...
Keep in mind. People lie (er...embellish) about mileage more than any other things IMO. Ever hear of the one ton crew cab 4x4 diesel getting "29 MPG"?.
I drive for mileage too, I never seem to get to the hige end of "reported fuel mileage"
Your mind may have been made up when...
I would really research the Toyota MPG. I don't think you will see 22 from a double cab. I would bet closer to 17 unless it's bone stock, then maybe 19?. Lots of people seem to have trouble calculating and reporting honest MPG but maybe some will chime in here.
Good choice. I have a 96 with the 7.4L and it's nothing special in the power department. Not enough to justify the fuel mileage. I love the rig and might end up doing a 4BT swap but if I was buying again and not towing a heavy trailer I would look to a 6.0L sub.
None is the short answer. If you fear the Duramax any 6.0 will be a living nightmare! Google it. You can throw many thousands at one and get it reasonably reliable. I always vote Cummins.
6.0 problems go way beyond heads.
