yup! Lotsa squeeking can come from the WDH situation that you have. Currently we have Equalizer, but before that we had a Reese and several others over the years and we still had some major squeeking!
But I can tell ya, the one that works best with our F-150 and Jay flight G2 29bhs set-up that allows us to travel at 65mph in wind with no sway prooved to be the Equalizer. Man! That sucker still squeeks on the turns though! (just like the other companies we had over past couple of trailers).
