I'm using a 5/8" x 4" hitch pin (found at Tractor Supply), having drilled out the clip hole large enough to insert a pad lock into - to prevent someone from stealing the 2.5 & 3 inch adapter inserts.
I do this on our coach too, to prevent someone from disconnecting a trailer or tow vehicle while towing (or sleeping in rest areas/truck stops etc).
I've heard the inserts are pretty expensive & while this isn't the prettiest solution it works well.
On 2 inch receiver's you have enough length to still be able to insert the clip (close to the receiver).
Sound like someone is a little paranoid. I guess it better to be safe than sorry huh?
its not so much about theft for me (not that i have seen any available 3" - 2.5" adapters available for purchase either), for me its about not having to look a KEY to lock/unlock the hitch pin on 4 different vehicle.

That Master Lock you're using is probably a 5/16" shank. Would a 3/8" hole be too tight?
