Question:

My 2020 Ram 3500 receiver is 2 1/2. Ram provides an adapter sleeve for 2inch hitches. My problem is that the Ram 3500 receiver has a 1/2inch pin hole, the adapter sleeve has a 5/8inch pin hole, and my 7,000lb RV trailer has a 5/8inch pin hole. Sometimes when towing I can hear the trailer hitch hit the pin because of the difference in pin hole sizes. My trailer dealer says this is ok, but I still wonder. Do they make hitches with a 1/2inch pin hole, or should I drill out my Ram 3500 receiver hole to 5/8, or just not worry about it? Thanks

Expert Reply:

We have never seen an 1/2" diameter hitch pin on a 2-1/2" receiver. They all have 5/8" standard. We only see the 1/2" pins on the small 1-1/4" receivers. I would measure your hitch pin carefully. Is it possible that everything is 5/8" but just has a loose fit? Hitch parts do not have tight tolerances and tend to wiggle and rattle a little. Most likely your setup is just fine.If the rattling becomes annoying you can always add a Trailer Hitch Anti-Rattle Kit for 1-1/4" Trailer Hitches, Item # F-315
