I would/Did last 4 VIN-2" numbers.-never my ph #.Thief allready has your
registration he knows where you live. in my case---i use po box for
registration, but GOVT is going to change that,so they can find you, adding some sort of "key" word might work-"I have a different one" other than Last name, i use for that,or just first & last initial like my tools have..I also have big link Chain i put thru the spokes when parked in a CG around (1) wheel but i rarely drive off & leave Cassie, Vunerable.and the anti sway (never) where it can be stolen AGAIN. i was in a VA state park someone stole the tention bars at night ---i had to buy the whole thing, can't replace just the bars,
it's a shame things have become a thiefs paradise,,IE shore power cables get cut--gone in a flash-.
take care.
