Abstract: A weight distribution measurement system includes a portable measuring device configured to measure a linear distance and store a plurality of measurements. The portable measuring device is also configured to measure a first distance between a first location on a vehicle supported by an axle of the vehicle and a second location, wherein the first distance is measured prior to loading the vehicle. The portable measuring device is also configured to measure a second distance between the first location and the second location, wherein the second distance is measured after loading a vehicle. And the portable measuring device can measure a third distance between the first location and the second location, wherein the third distance is measured after loading a vehicle and after a weight distribution mechanism has been engaged, and then calculate the percent weight distribution over the axles of the vehicle using the portable measuring device and display the percent weight distribution.
