[split] Well, she bit the dust, In Frame this week...

First off, you stated it's a thousand h/p and I doubt very much you will ever even come close to 1.3 million miles with that kind of power. I also don't think you can even come close to mpg's of a "Mandate removed cummins.
Yes you will probably blow the doors off anything on the hill but in the end, you will have much greater expenses in tires, bearings, rearends, transmission related problems just to mention a few due to all that un needed power you have there.
The second thing you mentioned was getting into a shop.
I see you have put your faith in their shop instead of taking control of your own business. I'm just saying. Most guys can run the cummins well past a million miles with or without a mandate once they are educated and stop relying on the stealer ships to save their ass. I know this because I'm one of many who do so and I work with drivers every day that learn NOT to rely on someone else for somthing they can do themselves.
But I gotta say, that's a pretty looking thing you got there.
Good luck friend.
