Equalizer hitch necessary???

I let a friend use ours because he complained of high cross winds out west, an area that he frequents, saying he had trouble keeping the trailer running true. When he returned home he told me he had ordered one due to using ours and how fantastic they worked.
Regardless of the TV you have safety should be the primary concern. We purchased ours after seeing a RV on it's side on I75 about ten years ago. When stopping to see if I could help I was told cross wind caused the accident.
