TPMS saves the day!

I was towing my rig north bound on I-75, just north of Macon, GA when I heard that dreaded "beeping" sound. I looked at my Pressure Pro TPMS and it showed low air in the left front trailer tire. I put on my flashers and pulled over before it went totally flat, saving the tire and avoiding damage to the trailer. After putting out my safety cones, I got to work. Fortunately I travel with a cordless impact wrench, so I had the tire changed and was back on my way in 15 minutes. I couldn't get very far off the "fog line" because of the narrow shoulder, but the flashers and cones helped to move most of the drivers over a lane and give me a little breathing room. The only close call came from another RV'er who apparently doesn't under stand the concept of giving a disabled vehicle a little breathing room. By the way, there was nothing wrong with the tire (Maxis), the valve stem failed.
