Go to your local hardware store and buy a pack of plastic shims. The kind used to install doors and windows. Drive the narrow end into the receiver till tight. Break off remainder sticking out. Solid as a rock!
I tried this, a few issues, for one unless taped, the shims will eventually work their way out, secondly, when they are jammed in there it's almost impossible to get the ball (or whatever you have installed for towing) out. Imagine jamming in wedges which also wedges whatever device you have in the receiver and now that the shims are broken how do you remove it? And left with broken shims, what do you do next time? New shims?
Ahhh, you just confirmed what I suspected and mentioned in previous post, Effy. Don't think I gonna mess with shims, as we do have to take the tow bar out from time to time, to put a bike rack on back of the Motorhome to carry bikes instead of towing.
The solution I proposed earlier works great and is so simple not to mention free if you have the tools. Simply drill and tap a 3/8 hole in the top of the receiver, screw in a bolt and snug up when you are towing, back off to remove. Easy cheesy and works like a charm. Took me a total of 5 mins and was free. Been using this method for 5 years. Never any movement, never any issues. And takes only a few seconds when hooking up. Nothing to remove or add.
I like that idea, but my issue with it is, I worry about that weakening the hitch receiver and causing much bigger problems.

I was concerned about this before I did it and approached my local metal shop and posed the question there. While there is some lateral force on the end of the receiver, it's usually equivalent to a few hundred pounds max and most of that is on the bottom and some on the sides. Very little if any on the top. The real stress is at the pin point. So if you drill and tap the end of the receiver technically there is very little if any change in structural integrity. One could argue that limiting play would actually reduce some of the shock force. Been doing it on mine (both my truck pulling a large boat and the MH towing the car for 5 years and no signs of wear, ovaling of the hole, or any signs of stress. Still works just like the day I did it. As a worst case scenario, even if it cracked at the hole, there is no way this would impact the area where the actual pin is.
