Vehicle security for long road trip

My wife and I are taking one of our Darts on a long distance road trip (2 months) this summer and plan to do the same in 2024. I am looking for people's experiences with various types of security systems for cars. I am particularly concerned about being parked outside hotels at night or in a restaurant or tourist stop. I have looked at various systems to track the car, but many these days plug into you OBD port (something I've never had). So suggestions on how to keep the car from being dragged up on a rollback and disappeared, or tracking it if someone does manage that would be really welcome.

I get even more nervous when I see stuff like Hotchkiss' car, trailer and truck being stolen!!! I'm afraid that a nice Plum Crazy car is just too much of a magnet for this kind of thing.

Thanks for your help...

I'm looking into the same thing and I think Apple Air tags would work as a tracking device. Just stick one somewhere it can't be readily seen and you can track it wherever it goes via your phone. Unfortunately, it can't stop the car from being stolen in the first place.
