ive had gas taken from both of my toyotas now. both siphoned i believe. the truck i found the cap on the ground and didnt even realize it was mine.
took bout 3/8 tank from that. got a locking gas cap after this.
itll help at least, probably makem move onto the next rig insteada mine at least. which sucks for whoever else, but sorry.
the runner, i left the door unlocked (no windshield anyways) and they went in and popped the door for the fuel cap and took about 1/4 tank from that.
