Drill and tap 2.5" reducer
What you might consider doing is tapping the receiver (2.5" side) and putting a hole in the reducer. You can lock the bolt down to the receiver and not worry about any play (jam nut, lock washer, loc-tite, whatever method you want to use to ensure the bolt won't move). Have the bolt go most of the way through the reducer sleeve (BUT NOT ALL THE WAY THROUGH!). This will lock the reducer in place, still allow the drawbar to go in, and it will still keep the small amount of movement in the set up without worrying about the bolt working loose.
If you do tap the reducer and use it as a nut - do it on the side or bottom, not the top. If you do it on the top the bolt will be pulling the reducer (and everything in it/attached to it - trailer tongue) UP. As you drive down the road the weight and vibration will be constantly stressing that bond.

Exactly what I did. Stainless 1/4-20 bolt 3/4" long. There is a circular hole about the size of a quarter on the bottom of the trailer hitch, right in the middle of the receiver tube about three fourths of the way back. It made a perfect place to drill, and reduced the layers you need to drill through.
If anybody cares here is a step by step. (I hate uploading picts, so not gonna happen! I'll leave that to Epic. )
1. punch in the center of the quarter sized hold to keep your drill bit on target.
2. with the insert locked in by hitch pin, drill through the outside receiver, and when you feel it go through, let it keep cutting into the sleeve a bit to mark it for you and start a hole.
3. remove the sleeve, and tap out the hole in the outer receiver
4. Try your bolt and see how far into the the receiver it goes. Should be just a bit by the time you put a lock washer on the bolt.
5. use a 1/4" bit and drill into the hole you started on the sleeve. Don't need to go all the way through, fust enough to give your bolt some room to avoid the forces when towing. (If you accidentally go all the way through, it really wont hurt anything, just might dap some paint on the hole to avoid rusting.
6. back the bolt out a bit, slide the sleeve in and put the hitch pin through, turn the bolt in, check your work, and you should be good to go for the next 10 years. No more pin the tail on the receive hitch game for you,

In the unlikely event you ever want to pull a house, you can loosen the bolt, remove your insert, slide in a 2.5" hitch head and tow away that house.

If you zoom in around the pin what you see behind it is a countersunk screw holding the adapter on.
