BAHAHHAHAHA This post is hilarious. So funny I didnt even read the rest of the thread. PMR's wont fail at 200k. Completely untrue. PMR's fail due to advanced timing and running anything north of 400 HP, which I doubt the OP will do. And a 5.9 making 1000 hp on stock internals? Keep dreaming. It's been done but it is no where near reliable. You should do some more research and put down the diesel power magazine. My 7.3 (01 with 320k miles) with PMR's runs like a champ, gets 20+ mpg unloaded on the highway and 12-14 depending on what I am towing. My 05 6.0 got about the same mileage but had alot more towing power. It was a blast to drive and never gave me any issues in the 20k miles I put on it. I know several people with reliable 5.9 cummins that have the same power and get the same mileage. Pick what truck you like, test drive the $hit out of it and get it. Once you go diesel you will never go back to gas.
