Happy to say that my wife and I, along with three small children (4, 2 & 1) are the proud owners of a FR Flagstaff Classic SUper Lite 31QBSS. Just need to figure out how to manuever this thing as I have never pulled anything behind the Suburban in my life.
Congratulations. Find a big empty parking lot and practice backing into a stall. Take some cones with you if you have them and set up a "backing course" and practice up. You might also find this helpfull: Backing Setup Maneuver
