That's a pretty good price for those options.

Unless you have to buy it right now, I'd shop around (try carmax, they usually have some good prices and easy to navigate site, plus they transfer your truck for free if it's close enough) local dealerships. If you are going to use that tow package I'd hold out for a 4.0 and pay a little more (maybe even same price). They get pretty much the same MPG and have more power/torque for towing.
