Any of the popular base plates (BlueOx, Demco, or RoadMaster) will work fine. Check their websites for compatibility.
Tow bars, same story. After having used BlueOx for a few years, I switched to Demco. Much easier to use and setup.
Braking systems - Since you have air brakes, built ins like the SMI Airforce One or the M&G Brake are an excellent choice. If you want a portable brake, the best and easiest to use is the RVi Brake.
Look for plug and play light connection kits and systems to provide a charge line to the Jeep (RVi and others) and you will be all set.
