Greetings fellow travelers and tax payers.
I have inherited a complete 'Pressure Pro, Tire Pressure Monitoring System.' Hand writing inside the box, "Tire Trak Sys. P/N RV6 $470.00." The system does not show evidence of use.
Is this a reliable monitoring system? I am assuming the Sensors are battery powered. How long would these sensor batteries last sitting in the box. I don't see anyway to install new batteries.
Is it a good idea to have this system installed or is this just another gadget? I have done without it this long, but it was free

and I have plenty time to work with it.
Any help is appreciated. Thanks.
