We had never towed before and decided to give it a try because our style of rving changed.  We are going further for longer periods of time at one place and we normally boondock.  A highly recommended local RV independent guy suggested the Roadmaster Falcon and the SMI brake system, just as several other posters in this thread have suggested. 
Yes, it cost a little more but we can hook this up very quickly and all the visible stuff is left attached to the RV and that allows for a very clean look to our Jeep Trailhawk.  Since this is our first rodeo with towing, I am so glad we took the guy's suggestion because it works perfectly for us and stops on a dime.
