If you know how to secure your old truck the only way it could be stolen is with a tow truck or flat bed.
?? Chain it to something solid? Even that's not theftproof.
I locked a chain around one wheel of a cargo trailer and also to the tongue when I had to leave it on the road. My only thought was to make it harder for someone to drag it off. They still could but would smoke that one tire going down the road, or they'd have to have a different wheel to bolt on. The only real way is to make it hard enough for a determined thief to look for an easier target. JMHO.
