I was recently looking at the millions of different GPS trackers available for cars, RV's, boats etc and just wondered if anyone had any feedback on any particular brands or services. I presume you need some sort of subscription or cell plan for them all which I don't like but they seem like a great way to protect your toys. I would like them to simply alarm if my toy leaves the area it's supposed to be in and also provide current location so I think most of the basic ones would do the job. Any experience good or bad?
