Glad you got the truck back.
I have 3 anti-theft measures on our "truck", none of which I'd outline in a Forum.
What always worried me, was the value of the truck (ours is a 2004, in absolute mint condition). I had to have it re-evaluated for insurance purposes, because without the re-evaluation, we would only get 10.3 cents on the dollar in compensation. So, we'd only get about $8000 if stolen, for a mint 2004 truck, with very, very low miles; and would have to pay over $79,000 CAD for a replacement.
I also had the camper re-evaluated, too.
