It has been my experiance that these wont work,the added weight ofTPM will fatigue the rubber mount in the rim,cause rapid air loss, but the TPMS will noteify you.

I must be in dream land, my 507 has been working 4 years now on rubber stems and not losing air pressure.

That is nothing more than a cheep valve cap that may change color to red if pressure is low. Of course to be a real TPMS you would need someone to run beside your trailer to watch the cap to alert the driver when they change to red.
IMO a bit of big BIG stretch from real truth in advertising to call that a TPMS.
If your dealer tries to tell you that is what the valve cap is, do a quick Google of the term TPMS and show him what comes up.Colored valve caps sell for $4 a set.

Been running our 507 on rubber stems for three years and no problem. I inspect them before each trip. I remove the sensors when not traveling to keep from running down the batteries.

I don't think the problem is the use of what appears to be a standard passenger low pressure tire valve with a colored valve cap.
I see nothing that looks like any real TPMS in the picture. Personally in my opinion, I would consider selling a valve cap as a TPMS is close to a scam.

That is not amTPMS sensor. It is green because you have nitrogen filled tires. You need to talk,to dealer and get your sensors and monitor.
I too am running on rubber valve stems for over a year. 6000 miles and no issues..

Unless there are sensors inside the tires and they gave you some kind of box that they send signals to, they either ripped you off or they forgot to add the TPMS

Unfortunately, that is their idea of a "TPMS". Green at the proper pressure and turns red when it falls below.
I too was supposed to get a TPMS. I smelled something funny when the dealer said they would "throw it in no-charge". I asked about it upon delivery and they pointed to those caps and said, "there you go!".
Ummm, nice try.

"No That is nothing more than a cheep valve cap that may change color to red if pressure is low.

But I can also see FR calling them a TPMS, to them that is what they are...

Maybe next "feature" from FR will be:
A "Hot Engine in the motorhome" just leave water out of radiator
"A/C" a block of ice and a fan to blow air across it
"Entertainment center" Old transistor radio duct taped to the side cabinet in RV
"Stone counter top" Bag of pea gravel glued to counter
" Three burner stove" Metal box with 3 cans of Sterno
All joking aside, NHTSA has a definition of TPMS that includes it functions. I wonder what they would think of FR offering a $1 valve cap as a substitute
