Yeah BUT what if there towing the yodas or puttin em on a rollback ?
Back to the LoJack, It might get away, but not for long.
You could put all kinds of gear locks and stuff to keep it from rolling, but it is no problem to drag it up on a flat bed or dolly it unless you chain it down.
I have a 3/8" case hard chain holding my trailer to a 2'x2' block of concrete 3' under the ground, but even that isn't fool proof.
