Tire Pressure Monitoring

Has anyone taken the plunge yet and install a tire pressure monitoring system on their pod? I have seen a few nice kits on ebay, some where the tire would have to be removed to install and others with monitoring valve caps.

The August issue of Trailer Life has an article about tire pressure monitors.

I have a pressure monitoring system on my Pod. The sensors screw onto the tires.  There is a display that plugs into the dash.  I originally bought it for my RV, so it has a six sensor display.  I only need to display the two Pod sensors because my new TV has digital internal tire pressure display.  The purchase price was quite high but was told the sensors activate only when tire pressure is higher than ambient pressure so six sensors should last quite awhile using only two at a time.
I like the idea of being able to detect drop in air pressure while en-route.  The few times that I have had low tire pressure was picking up nails or road debris.  I usually check the pressure when I stop and buy gas.  The leaks would have caused major tire damage if I hadn't noticed a drop in pressure while traveling.  The sensor(s) gave me enough warning to stop at a convenient rest-area and change out the tire. More than paid back the cost.

Our TV came with tire pressure sensors. We've been alerted to low pressures on 2 occasions. Both were false alarms. Not too impressed with the system.
