Tymate Black

This TPMS is available through Amazon. It comes with four, 87 psi sensors, supports 2 axles, and spare tire monitoring. It has user settable alarms for pressure and temperature. The receiver/display can be charged via usb or by a built in solar panel. The display cycles through each pressure sensor. I first put all four sensors on my TV which had its own  manufacturer's TPMS. All sensor agreed within 1psi, possible as good as 0.7 psi. With the Tymate sensors on my TT (1575), I never incurred a signal loss with the Tymate receiver (it has a non-skid pad) resting on the TV dash. Depending on ambient lighting the display is a little difficult to read. However, I would rely on the audible alarm while moving. The instruction manual could be better written, however at $70 it is a good entry level system.
