Do remember--the further back you place anything in your rig, be it in the basement or under the bed, etc--you are really adding more weight to your rear axle/tires than just the weight of stuff you put in. It is like the opposite of a lever. There is a formula you can use to calculate it. You have plenty of available weight on the front axle--try and place the heaviest stuff up front, and the lighter stuff in back. If your fresh water tank is in the rear, like most rigs, consider hauling 1/2 tank or even less. Don't haul your sodas, etc--wait till you get to your destination to buy them. You're already at your limit of 80psi on your LT tires--so be careful and once you are on the road--stop at a Flying J or Loves and get another weigh with everybody on board and in the position they travel in.
