second tpms - Tire Tracker system October 25, 2010, 05:28:19 pm Yahoo Message Number: 117758Richard, I am currently using the Tire Tracker for both vehicles (LD & toad). I did get the optional repeater and stuck it to the rear window of our 27' RB so the toad would be in range. You need to really study and follow the installation instructions on programming the sensor locations. I took a scratch pen to the plastic cap marking each sensor's permanent location on both vehicles. Also carry a spare sensor button battery (found @ Radio Shack). I have used the system for the last 9000-miles and it works well. Mike[Non-text portions of this message have been removed]
