The Monitor can be taken out of the RV, for instance, and put in the towed car, or on a truck or any other vehicle, using the cigarette lighter plug.

Likewise, the Sensors can also be removed and put on a boat trailer, horse trailer, 5th wheel etc.

They will automatically adjust to the new air pressure and set a new trigger pressure for those tires. And if one buys a new vehicle, it is easy to "switch out" the system to the new vehicle.

Even if the Monitor is hard wired, it can be unplugged from the hard wire; then using the cigarette lighter plug, it can be moved to an alternate vehicle.
