If you are hauling a travel trailer and tongue weight and sway are getting the best of you, you may need a weight distributing hitch.  A weight distributing hitch allows you to haul a heavy trailer with a lot of tongue weight.  This hitch transfers weight back onto your vehicle's front axle through a torsion method implied in its spring bars.  When set up properly, these hitches can drastically improve the ride and stability of your vehicle and trailer.  And they almost always in general increase your hitch capacity, most of the time doubling it!  See the video below to watch how it works!
