eTrailer's take on the BO verses the Reese Dual Cam.
https://www.etrailer.com/question-116001.htmlI recently bought a barely used Equalizer 4 point 10k for our 32.5' TT. I torque the socket bolts to 65ft/lbs and grease the socket friction points per the manual. I also break the rules and rub a little grease on the L brackets. That's not a recommendation for others. Just what works for me. It's smooth and quiet and no waggle from passing trucks.
I think the occasional pop is the shank swapping sides in the receiver. Just a guess though.
