Joe, I have Tire Minder on my coach and toad. It comes with an amplifier that I installed in rear engine compartment so signal from toad is no problem. Also, batteries are replaceable. The only issue I have had is the batteries go dead once in a while. If you send the dead batteries back to Tire Minder they will replace them for free. You can also isolate the coach from the toad on the monitor so when you disconnect you can take monitor with you while driving toad. They make two models, one sold exclusively thru Camping World, the other model can be found cheapest on Amazon. Also, they sell extra sensors for your specific needs. Shop around on Amazon and E-bay and you will find what you need. Hope this helps, Frank.
