I doubt anybody would steel the step, but for some reason, hitch pins do walk away shockingly often.
The bolts and some sort of locking nut(s) was my first thought as well.
As we also agree there's little chance of someone stealing the step assembly but even so I'd like to at least be able to slow potential miscreants down a bit.
I like the B.O.L.T. stuff---would be very handy NOT keeping extra keys. Since I already hide an extra key on the frame I'd always have one. FWIW that's interesting the key learning feature works. If I go that route I'll find a why albeit messy to keep as much moisture as I can out of the lock cylinder, perhaps pack as much grease inside before placing the cover. Perhaps bit wrap or two of Gorilla Tape?
Even though I'm using a total of 4 hitch pins I could make do with only two. I've drilled and tapped 3/8-16 holes in the frame mounted receiver and another element which serve to stop the whole mess of tubes from rattling while driving. Along with jam nuts that's a fairly solid step at this moment---no rattles and very firm feeling under the feet. For the most part simply pulling the hitch pins doesn't let any part come easily loose so that's an added benefit in my mind.
Thanks guys---I've got this one mostly sorted and will report back if there's any interest in the B.O.L.T. locking hitch pins.
