IF you dont change your gears, you will never see the full potential of your truck. just as gas guzzler is saying, You are running over size tires and pullng a trailer. change to a 4.10 if you want to keep the tires you have. 4.56 if you want to go bigger. I have 33s and i pull a 3700 lbs car on top of the trailer. The first chance i get i am gonna regear. And as, prior stated, you will wear out your driveline and drivetrain faster.
