Tell me about it, I've been looking for a hitch, I came across a MasterLock unit which has a key in the side of the hitch, which when turned, pushes out two pins to lock it into the receiver, this more or less just makes it so you dont need a separate hitch pin/lock however I didn't see if it would be a tight fit in a 2". I doubt it, everything needs a little play just incase of slight changes in tolerance and then not fitting at all.
One very cool thing my new THULE bike rack has is an anti sway hitch, and how they do this is by having it threaded.. So their pin threads into the hitch through the hole on the receiver just like any regular pin, but its thread, thus locking it in place.. Then a lock goes on the end of the pin/threaded unit to make sure no one can unbolt and steal the bike rack/bikes etc.
