    It's usually due to the HD emissions package used on heavier GVWR trucks.Air pumps,bigger or extra cats,ignition dwell\advance curve changes,etc can add weight and reduce performance or HP ratings.

    bobge - welcome to Plowsite

    You GVWR should be on the drivers door sticker,along with the FAWR (front axle weight rating),and the RAWR (rear).

    The rear end ratio should be on a tag on the rear diff cover bolts.
    If not,you will have to calculate it by counting the number of turns of the driveshaft required to get one complete rotation of the rear tires.


    Your maximum GCWR,or Gross combined weight rating should not be exceded when pulling a trailer.Pin weight plus cargo\passengers\fuel,etc should also not exceed the RAWR.Not sure what the GCWR is for your truck.Check the owners manual under towing,or check with your local dealer.They will need the VIN to check it.

    How big is your fifth wheel ? You will also have to hook up the electric brakes as well.

    If you look inside the glovebox, you should see a list of codes (RPOs, or regular production options).

    GT5 = 4.10
    GT4=3.73
    GU6=3.42
    GU4=3.08
