Stick a gasoline V8 in it (or a larger turbo-diesel), get closer to the concept interior dash center stack, and GM will have my order placed the next day
I don't haul a lot of stuff and I'm so used to driving my S-10 Blazer, that I don't need nor do I feel comfortable in a full-size truck.
A bonus would be to have a 4WD system that is easy to modify. You can bet your ass if I get one of these, it's getting a lift kit and bigger tires
