I picked up one of these:https://rhinohitch.com/collections/2-5-receiverI really like it as you don't get a stub sticking out below the hitch when you set it for a lower drop. Easy to adjust and I love the quick change ball system as I have trailers with three different ball sizes.The only downside I have seen is that for trailers with chains that are already tight, you might need to add a link or two, or upgrade to longer chains as the hitch sticks out quite a ways. I think I had to get a new chain on one of my trailers, the others were all fine.
