So what's out there? I would prefer no subscription cost and a stand alone unit that can be secretly attached under a trailer. The trailer will regularly be used by people other then me and I'd like to be able to keep tabs on it.
I've been looking all day and this seems to be the best option. Completely self contained with 5 years of batterey and 3 years of service for $279. Basically disposable when the service runs out and you average under $10/ month.
