While at the 2014 international goshen rally I purchased a tire traker 4 tire monitor system for my sabre, and I have to say I'm quite please at what I got for the price.
It was vary easy to install and gave immediate results.
Installation involved installing four new batteries that were supplied, setting the monitor up for my trailer tire pressure and then marrying the sensor to each wheel with the monitor.
Total install time was just a mere 15 minutes.
I occasionally looked at the pressures and tire Temps on the way home from goshen and noticed one sensor didn't quite look accurate for the temperature portion so I'm going to call tire traker this morning and see if I have a faulty sensor.
btw the tire traker has a three year warranty.
Just an fyi.
