guess I should serious for a min... I have disconnect switch, dummy coil wire( vaccum hose with nipples on each end) and depending on how big of a hurry I am I also unscrew the starter bolt..
I also leave unlocked at times.. my old international was broken into yrs ago at one of those rental places.......they made a big mess and took nothing.. wasnti anything to take.. so I wonder if isnt just as good not to worry about it and leave it unlock.. anything of value take out .because if they want they can make a big mess out of it.. this thought would only be if you have it insured.........
