Active - level rear Air Suspension!
An option available on specific trucks, is this auto air suspension. I currently have air bags that require me to add air when the box gets weighted down below level. Some of you may have this option ...

Auto leveling air valves, some have a dump port - are the easiest answer. With just about any onboard air supply, and s single valve located above the diff you have a constant level at the rear. Twin valves located as close to the tire as you can fit them with clearance for chains and flexing will give you side to side leveling as well as a constant rear level. The compressor is the biggest cost, then the valve(s), then air tank (.5 gallon is more then enough for leveling) and a pressure switch (or two). I am running two pressure switches, and two different pressures. The higher pressure rating runs the compressor, the lower one runs a buzzer - if the tank pressure drops below the cut in pressure by x lbs the buzzer starts, and continues until the pressure is above its cut out pressure - the tank compressor continues to run until its higher pressure switch's cut out pressure.
