Has anyone tried one of the anti rattle clamps that goes on your receiver/hitch to reduce the play that causes the clunking and banging around when towing? I've always wondered why these hitches/receivers weren't made with tighter tolerances to reduce the movement of the hitch. All of them seem to be this way though. I pull a 31' TT with a 2500 Sierra crew cab using an equalizer bar type hitch. The trailer is about 6000lbs empty. It tows great but sometimes clunks over bumps or driveways. I want to try one but don't know which type clamp to try.
