This is how I secure my generator. I use a cable lock through the handle to the tie down hooks in bed of truck. That slows them down. Then I cut a slot in the bed of the truck where I store the generator. I wrap a "J" strap around the axle of the generator and the flat part of strap goes through the slot cut in bed of truck. I then put a lock on strap that is now on the bottom side of the bed of truck. I can't figure out how to attach a photo.
