A better TPMS?

[George32940]

I had a 38' 2018 Tiffin Phaeton on which I installed an STS TPMS (no repeater). It worked great. I traded the Phaeton in for a 2024 40IP Bus. The Bus has its own TPMS so I'm just using the sensor "buttons" just on my toad. Sitting stationary (i.e. parked) the STS reads the toad tire pressure just fine. However, once the Bus is moving down the highway I lose the toad's tire pressure reading. I tried putting a repeater at various places inside and outside the Bus but to no avail. The monitor will not pick up the toads tire pressure. I suspect, since I'm not using the STS sensors on Bus' tires it's not going to read JUST the toads tire pressure.
Can anyone suggest a better TPMS that will work with just the toad?

I use TST 507, with repeater, but I am a lot shorter than you.
