No. if I get another one it will have but where do you stop spending
You could have hidden an airtag type of device, they're cheap as chips, I had one hidden in my van when I had it and now I have one in my car.
There was a chap on the news earlier in the week who had one hidden in his Range Rover, it got stolen and he tracked it to Tanzania, so they can work.
Sorry, I know it's no help now but maybe worth thinking about if you ever replace your caravan.
