Absolutely love this truck. I had two hemi's before this, they never even came close to the power and fuel mileage with the cummins diesel. I average 20 mpg. The only draw back with this truck, is do not let it idle for long periods of time. The emissions will give you troubles if you do. If you like to leave your vehicle idle, i suggest the emission delete kit. This truck is the mega cab, Laramie short box, single rear wheel.
