There are a number of WDH/Sway control setups that do both out there, just do your research and find what works for you. No one in my area keeps the Equalizer in stock. I went to the local trailer supply dealer and got the Curt 17501 system. I have no problems in high winds or buffeting when 18 wheelers pass from either direction with my setup.
I think my setup is a little overkill, but can we all really be too safe?
