As I mentioned a few months ago I was going to put an AirTag in my truck, so as a result of this thread I started experimenting with an Apple AirTag to track my vehicle and so far after a couple of months I've been very pleased with the results. Basically, I can say that it works well and is worth doing. No service fees of course beyond the price of the AirTag which was on sale at Amazon for $27.00.
In April, I had a problem with my truck that required a lot of road testing at my mechanic's garage and they gave me a loaner vehicle for a couple of days. The shop is about 12 or so miles away over in New Hampshire. Using my iPhone I could easily track the whereabouts of the truck at the garage and when one of the mechanics was out road testing it. It was my first major test with this thing and it was really kind of cool as I otherwise use AirTags to keep track of my house keys and wallet. The AirTag is said to not be as fast or accurate as a dedicated GPS tracker but it works pretty well and it was easy to locate my truck and follow it on the "Find My" app map on my iPhone.
This first thing I did when I got this AirTag was to remove the speaker so that it won't alert anyone that it is there if I am not around. Initially, I had the AirTag hidden in the map pocket on the back of the driver's seat. Recently, I did an upgrade that is giving me greater BlueTooth range as the Airtag is no longer inside the metal cab of the truck. Now, I can often (but not always) locate the truck in the parking lot of a big box store if I should happen to forget where I parked. Sometimes this will depend on if someone with an iPhone is within range of the AirTag as to how far away I can track the truck but with billions of iPhones out there, there's usually somebody around. The near field direction finding location capability works via Bluetooth and that will only work within 10 meters but once you get within that range your phone will point you right to whatever AirTag you are looking for. It's like a game of "hot & cold" as your phone tells you if you are getting closer or going in the wrong direction.
I purchase a waterproof case for the AirTag on AliExpress for $3.50. It's really designed for use on a dog collar but it can be used any way you like. It is well made and very rugged with a rubber gasket and four heavy duty hex screws for closure that screw into brass fittings. It comes with a little hex wrench and straps with screws to attach the case to a dog collar but I didn't use those.
I mounted it inside one of the small compartments in the walls of my truck bed on the "ceiling" of the compartment using 3M VHB tape. It is secure and hard to find. Like I said, it now has better range than when it was in a the map pocket in the back of the driver's seat inside the cab.
