Had a buddy use a 2inch ball for more than a year before I saw it and questioned the size, should be 2 5/16 inches.
I had a brand new boat that had a light tongue weight and would clunk but not just on braking, it was trying to come off the ball. Readjusted the boat on the trailer and all has been good.
I had a ball come loose once, found it loose at a gas stop, scared the heckter out of me(just had a chill thinking about it). At every gas stop I walk my camper and truck thumping tires, feeling hubs just doing a good visual on everything.
I am actually proud to have towed so much that I have changed out two hitch pins from wear grooves.
And yes, I am a brake-controller-adjuster guy. As the road conditions change I adjust; I like to use heavy-ish camper brakes and save my truck’s brakes but in stop and go traffic, rain, sleet or gravel roads I adjust them down a bit. I will also manually use the controller to save TV brakes.
Good luck, strange clucks and noises can drive you crazy.
Thanks for being responsible enough to care.
