Trailer TPMS sensors not reading intermitantly

[Andrew Best]

I have installed the correct TPMS sensors on my tri-axle 5th wheel toy hauler. The rear wheels, and sometimes the center wheels loose signal. I'm being told by my dealer that they only reach 23 feet from the trucks back bumper. That reaches the front of the tires on my second axle. There was nothing in the literature when I bought the sensors that stated the 23' limit which also makes no sense for truck that can tow 31,000 plus lbs. GM tells me there is no repeater available. That seems strange since I had an aftermarket system (TST) that had a repeater and worked fine. Has anyone had this issue and found a solution?

Same issue but no solution. A repeater is key.  I tried the TireMinder repeater, as it said it was 433.00 MHz.  Turned out it is actually 433.92...

I tried the EZ repeater no luck there either.
