Default Tire Pressure Monitoring Systems for Trailers

Hi - all in Gliderland,

I am picking up the subject of the tire pressure monitoring systems for trailers from another, unrelated thread.
I would like to hear more from others who have installed one on trailers. One unit was mentioned which looks very sophisticated.
Has anyone used this one, which is less expensive?

https://www.walmart.com/ip/GoSafe-TP...m #about-item

It has a simple readout but I am wondering if it would be able to receive the signals from a trailer - four tires in my case. I could install the receiver in the lighter outlet by the rear door of my van and just hope I will hear the warning tone.
Also, does anyone know if these systems operate on the same frequency? Would two systems installed on the tires of the towing vehicle and the trailer interfere with each other?

Search around caravanning sites and you can find TPMS kits with six tyre
sensors on offer. Presumably these are good for trailers since none look
rugged enough for use on trucks, but nothing I've looked at gived a
maximum reception range in its specification or says anything about
interference. Six sensor kits are a lot more expensive than four sensor
kits, but I suppose that reflects market size and need for a different
display.

In the UK I've found six sensor kits being sold on Amazon, eBay and from
specialist suppliers.

Contact the supplier for the tech specs.

Forget the WalMart stuff. Go for the better built commercial products such as https://tsttruck.com/ .

I would not expect units intended for cars to the range to work well with a trailer.

Picking up that thread again. I purchased a system on Amazon capable of monitoring eight wheels via externally mounted pressure/temperature transducers and used it for the first time on a trip from SC to NM and back (1,500 miles each way). https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
I had the tires rotated and re-balanced before the trip although the tech at the tire shop mentioned that the monitors made hardly any difference (He ran a tire with and without a monitor on the balancer)
Setting up the pressure and temperature limits is pretty straight forward. The receiver - mounted with the supplied suction cup on the windshield - didn't seem to have any problems picking up the signals from the trailer. The display toggles through each tire about once a minute or so. One battery charge kept the display/receiver unit going for the whole trip. The transducers go to sleep shortly after no rotation is detected to save their batteries.
It was reassuring to see that the tire pressure was holding steady within 1/10 bar. It was also interesting to see the tire temperature rise and fall as road-and wind conditions changed. The unit warns when there is a slow leak well before the lower limit is reached by trending the pressure readings..
When the trailer is being detached, it can be 'un-linked', so the unit only looks for the tires of the tow vehicle.
All in all, I think a TPM system is cheap insurance against a blow-out. One saved fender and tire will already pay for the system.
