The hitch for my camper as well as all of my pintle hitches use the 2” receiver.
I honestly only have 1 hitch that is a 2 1/2”. I’ve never noticed any slop or play. Once it’s loaded it doesn’t seem to move a lot. I’ve towed up to 18k on an equipment trailer with a pintle and that 2 1/2” to 2” reducer. Never had a problem. The advantage of the class 5 hitch is the higher rating on the truck. Their good for 18k. Class 4 I believe, is rated for 10k.
