TPMS Compatible with GMC factory installed monitors?

Does anyone know of an after-market TPMS system (for my motor coach) that would also work with the factory monitoring system in my GMC Canyon toad? (Without installing valve stem sensors on the toad). It seems like fairly simple technology, there would just need to be some way to "tap" in to the info from the truck system and send it to the monitor in the coach... am I dreaming?
