Hello Don,
You do not need to go that far.
Just use a brand new padlock on the chain that is mounted under the driver's seat,
wrap it around the steering wheel, than padlock it.
Also, as with any vehicle, do not keep any valuables in your M1009.
Park it in safe locations..
Keep the windows rolled up and doors locked at all times when left unattended.
Sometimes it may come in handy if someone else has a key that will work on your M1009.
I learned this from experience not too long ago.
By the way, most of the guys that have these, from my experience so far, have been pretty good guys.
I think it would be very unlikely that any of them will steal your ride, just because they have a key to it.
Have a good day,
CJ
