I have the big air hitch for my 33' tt. I was concerned it would make it more sway-prone due to the extended hitch point-Not!! Takes out the shakes-except for less power, you absolutely don't know there is a trailer back there. . A big side benefit you might not be aware of is it corners better-ever see those trains at Wally World. . Unless you turn real short, you can see the whole trailer through your mirrors. One of the best investments for towing improvements (10000 miles a year)Love my Garmin Street Pilot, too. I never leave home without 'em!
