First and foremost, EGR& DPF deleted with ECM reburn. All after treatment components are in place and appear as normal visually, but the EGR cooler and DPF have been gutted. The truck has performed flawlessly since performing the delete 2 years ago. The truck is a pleasure to drive as it is smooth, quiet, clean and pulls great. The auto shift works flawlessly, even in the moutains. The computer can shift perfectly every time, I’ve never missed a shift since I started driving this one, wish I tried it years ago. Tires are about 70%, same with brake shoes. I changed batteries, starter, alternator, belt, tensioner, and coolant in March because I had to go to the Northwest territory, Canada for a few weeks, sub zero temps and the truck performed great, no problems. If you drive this truck, you won’t be disappointed. The truck shows much newer than it is. 4 battery APU. I am leaving CB (Cobra 29), XM radio receiver, and Truckers GPS
