If you are going to move into a new/newer GM truck, go with a 3500 and the 6.0 gasser with 4.10 gears. With the 6 speed transmission you should see 1 mpg better, both city and highway. Thank you for your service.

Good luck finding a 1ton gasser. They are like unicorns for a reason. More truck than the motor is meant to handle. 3/4ton + gasser just makes more sense. If your going to step up to a 1ton make it a diesel and do it right.
