I upgraded from a 2003 Chevy 1500 Z71 package. I'm towing a lot more now and I needed something with a little more umph. This truck has it. I thought about the diesel for this truck but I opted for the 6.0 because you never know when the prices are going to sky rocket again.
I love the fact that the trailer brake box is built into the dash. So, no ugly box hanging down to knock your knee on. The second fact is the six speed automatic. I like you can put it into manual mode to shift it like a manual for the steep hills.
A factory dualed off cat-back system with an air intake system to up the ponies a little more.
