A lot of em end up over in former eastern bloc countries. The gangs over there love big sedans/suv's/caddy you name it
Years ago when I worked at Dayton Freight, someone walked onto the yard in Huber Heights, and drove off with a twin screw, no trailer. Little did he know he took one off the ‘spares’ line. Two days latter he returned the truck, claiming he didn’t know Dayton, had such p.o.s. tractors. LOL
Remove the engine before going on your 34. If someone wants your truck they’ll take it. Only thing you can do is slow them down and make it harder but you can’t make it impossible.
If I was an 0/0 I'd have a secret cutoff switch for the fuel and one for electrical, plus a tracking device hidden somewhere.
