Tire monitor systems - aftermarket.

So the wife and I tow a toy hauler for our quads (full camper with a rear door that opens to drive the ATV s in, or golf cart or side by side) it’s 2 axle and 4 tires 80psi

Then there is my 24ft car trailer 2 axle 80psi.

So currently I have a valve stem cap that changes color of tire pressure lowers. A quick walk around every stop lets me know truck and trailer are okay. But I’ve been wanting to go electronic and monitor the 8 tires (truck and trailer) from inside the truck as we are rolling. Anyone here have a tire monitor that is aftermarket that they recommend? Last year when I checked there were lots of American companies that sold them. This year Amazon has about 5 of their own brands and I don’t recognize any of them.

Looking for suggestions.
