Sorry for the OT post, but I figure there must be a lot of trailer users in this group. This might be more of a vent than an actual question.
My old van had a U-Haul Class 2 hitch and I didn't know my trailer was back there unless I looked in the rearview mirror.
Last month I had a Reese Class 3 hitch installed on my new van and there is a lot of play between the ballmount (also a Reese) and the receiver. There is no mistaking that I'm towing something...you can hear it banging around on almost every bump and turn. I went back to the install shop and he said it was normal. He even mentioned that they make anti-rattle devices -
It seems to me that all that banging around has to put more wear and tear on the hitch and mounting hardware.
So, if I actually had a question, it would be this: If the rattle is so "normal" that they make a device to eliminate it, why not make the ballmount bigger or the receiver smaller and solve the root problem?
