Hello from a newbie (and a Keystone question)

On the hitch, regardless of which one you have, there should be a manual. If you don't have one, look online. For the Equalizer Hitch, for example, the manual has detailed instructions about how to assess, calculate and install the hitch for optimum results. In short, if the front of the truck is not squatting proportionately, you're not set up properly and are missing the intended benefits of the weight distribution. Every truck and trailer combination are different so the only way to accomplish optimum results is to work through the process.
