Question for diesel owners

To each his on. A lot of good info on here. I had a 2001 GMC CC Dually with a 8.1 gas and Allison automatic. Pulled a 40 foot tri axle toy hauler over the place Over 20,000 miles to AK and back to TX. with no problem plenty of power just 7 MPG. 3 years ago we switched to a TC bought a rig from a friend set up and ready to go. 2003 Ford F450 flatbed with a custom made aluminum bed with a 6.0 and a Arctic Fox 990 camper. I had a couple of problems right of the bat, alt, belt batteries, ecim, 2 injectors, tires, sway bars. But it was a used truck with 120,000 miles on it. I have put 30,000bmiles on it in 3 years with out a problem at all. Hope to put a lot more miles on it but if it breaks we will fix it and keep going. I am not going to spend $70,000.00 to replace it I can do a lot of repairs for that kind of money. Maybe not as fast as a 6.7. but if I was in that big a hurry I would drive a corvette and stay in a motel. Do your research buy what you want and be happy with it, don't worry about what every body else says.
