Thanks for the info. It definitely pulls the mowing trailer like nothing is there. I put my boat behind it which is about 6000 pounds and it pulls it very well too. I can feel it there, but still MUCH better then the Ram. To answer your questions: PMD has been relocated, but I am going to buy an extension harness and move it further. No EGT gauge yet. I am going to get one of those and a boost gauge soon. I did the oil cooler lines as soon as I got it. I have been reading a lot about them over at dieselplace..com. I upgraded them with the stainless braided from Heath? I think that was it. Any more tips would be greatly appreciated!
