This is the one that our rig came with, and it has the smart charging circuitry. I am pretty sure yours will likely have the same one, or possibly at least the 75 amp model. I would say, forget the Keystone manual for getting any brand specific information for any of the components in your rig. You should be able to get the brand and model number of your power center which is the converter and 12 volt/120 volt distribution center on the label you see when you open the door. If it is the Progressive Dynamics unit, you can get a copy of the manual at

The text I quoted is from the Progressive Dynamics manual, on page 4.
