Help on sway control and hitch

Tow vehicle is a 2013 Suburban with a very high hitch, pulling a R-177. Even with a 8" drop receiver with a 2" ball, the nose of the trailer is riding a little up. I am not using a weight distribution,or anti sway hitch.
On the interstate with a side blowing wind, the ride is a little rough.
Before I go spend a lot of money on something I don't need, what are your thoughts? What do I need to do to smooth things out?

I have had good luck with wind tabs I installed,dont have the pushing feeling when being passed by large truckc,just a thought.

I agree with Jdub, friction bar worked wonders for us and if you do it yourself it is well under $ 100.00 total plus a little bit of your time, maybe an hour of labor.

yup, friction bar should do the trick for you!

I held out for a year and a half before buying friction sway control for my rpod.  I had never encountered any major sway until a particularly windy drive up the coast of Lake Huron; even then, it wasn't too severe, it was just relentless (and tiring) for a couple of hours.  I decided to give a friction bar a try - frankly, its well worth it for the calming influence it has on the trailer.  The cost was minimal ($80 for the sway bar, $20 to have someone weld the tab onto my draw bar, the rest I did myself).
