TPMS alarm saved the day
Yesterday I pulled into a campsite in Albuquerque, NM just for an overnight stay.  I didn’t even disconnect the Jeep from the LD.  All systems had been working well when I stopped for the night, so bright and early this morning I headed out for Amarillo, TX.

I had earlier installed an aftermarket TPMS and it automatically starts when the engine starts.  It usually takes a few miles driving before the sensors register.  That’s when the low pressure alarm went off telling me the left inside dually was only 13 psi.  Odd thing was that it didn’t feel any different driving then when the pressure is normal.  Anyway, I take the next exit and find a good place to pullover and then get out the Viair air pump and gauge.  Sure enough it’s only 13 psi… I pump the tire up to 70 psi, wait 5 minutes and then watch the pressure drop to 65 psi.  As luck would have it, a quick Siri search finds a tire repair shop 2.5 miles away and they say they will work on the LD.  From the picture below, you can see what they pulled out between the tire threads.

I’m really glad that I had installed the TPMS system when I did.  As I said before, I didn’t feel any difference in the handling of the LD with the low dually tire pressure.  All it cost me was $20 and a couple of hours out of my day.  I don’t even want to think what it would have cost if I had continued driving until the other dually blew due to excess weight on the tire.

A TPMS can be worth its weight in gold, I'm glad it saved you from a lot of trouble.
It's another "must have" in my book, especially if you tow.

I got everything at etrailer.com.  I bought a TST-507 with 6 cap sensors for the LD and an extra set of 4 cap sensors for the toad and an extra set of 2 cap sensors for the LD and toad spare tires.  Not a cheap endeavor but IMO well worth the expense.

Installed the same system on my TK.

Works fine, but does have false alarms about once every two weeks, had another this evening.

Pulled over immediately the first couple times I heard the alarm, both were false alarms.   But since then, I first turn off the monitor then turn back on to clear the false alarm.   Never the same sensor either.  Still love it.

Some false alarms are obvious, like this one from early August, at elevation (Mt Rainer)

Dave,

I’ve had 2 false alarms with the TST-507.  Like your picture shows, they were high temperature alarms.  Both times the alarmed temperature was 330 degrees.  The first time I did as you said and cycled the power to clear it, the second time I just let it go an it cleared itself in about 5 minutes.  I knew a temperature of 330 degrees was not something to get too worried about 😉

Since the sensor is located on the stem, not inside the tire/wheel assembly, temperature readings can be deceiving and of limited value, unless the tire pressure is rising rapidly along with the temperature, indicating a possible bad wheel bearing or a seized brake caliper.

A better, heat-sensitive TPMS sensor would be installed inside the wheel, the same as OEM TPMS systems.
AFAIK, none of the aftermarket TPMS use an internal sensor.

Hi Larry;  The TST actually can be ordered with internal tire sensors. https://www.etrailer.com/TPMS-Sensor/TST/TST-507-INT-6-C.html   They are mounted to the wheel inside. Cost a bundle, batteries are non replaceable and last from 12 to 18 months. They require partial tire/rim removal to replace. Doesn't sound like a 'winner' to me. 
    Another system 'Tuson' also from Etrailer  https://www.etrailer.com/TPMS-Sensor/Tuson-RV-Brakes/335TPMS6WIVS.html?feed=npn&utm_source=google&utm_medium=cpc&utm_campaign=Google%20%7C%20Shop%20-%20Low%20Volume%20-%201000&adgroupid=140227600527&campaignid=10274415741&creative=597205810017&device=c&devicemodel=&feeditemid=&keyword=&loc_interest_ms=&loc_physical_ms=9061201&matchtype=&network=g&placement=&position=&gclid=Cj0KCQjw9ZGYBhCEARIsAEUXITUH_Issg3XBxYI7SUE6gRIN3H5vz9AK6xWWA-ze-EfwS07juTKW4DcaAtxrEALw_wcB  has 'at the filler' sensors with the above same drawbacks.    RonB

We have the EEZ System with Borg like valve stems.  The EEZ sensors screw onto the stems.  We’ve had this system for several years and we’ve not had any difficulties.  The 3V batteries last more than a year and actually close to 2 years.  I routinely change all the batteries somewhere around 18-24 months.

Hope this helps.

I also have Borg valve stems installed and use the TST-507 with cap sensors that I linked in my previous post.  No problems at all using the Borg valve stems and TST sensors.

Question about the "it automatically starts when the engine starts". I have the same one, but it lasts the better part of a week on battery before needing a plugg in.   I turn it on a day or so before the trip and checking the readings on rig and tow'd are part of the 'pre-flight' checklist every time the rig moves.   It does take  a while after turning it on to have all the sensors chime in.

I don't have a repeater, but with the rig beside the garage and the tow'd in the middle of 3 bays, all 10 come on line.

I’m not sure what your question is but I’ll try to explain why I set it up to automatically turn on when the engine turns on.  First of all I fulltime, so sometimes I travel nearly everyday and other times I stay put a week or more.  So charging on a schedule doesn’t make sense for me.  Second, the monitor is suction cup mounted to the windshield and it sits down low as to not obstruct my view out the windshield.  It would not be an easy thing to remove/charge/remount whenever the battery got low and it’s one less thing I have to remember to keep charged.

Setting it up to automatically come on with the engine is very straightforward.  I use the included cigarette lighter / USB adapter and bought a female cigarette lighter pigtail at an auto parts store (I don’t remember which one).  By using the included adapter and the pigtail I bought, I’m not using up one of the USB ports on the dash.  I tapped into one of the switched hot wires under the steering wheel and found a good ground for the pigtail.  I then tie wrapped everything out of the way and routed the included USB cable up under the dash and through an opening in the corner where the windshield meets the top of the dash.  Leaving the power switch on the monitor in the off position allows the unit to automatically turn on when power is supplied to the USB cable.

I’m glad your way works for you.  I just find this way suits my lifestyle better.

Thanks.  So you have it wired into a switched circuit and leave its power switch in the off position.  I've noticed that it is on when plugged in even if the power switch is 'off'  Your way works for you, that's what counts. 
See you down the road sometime.

TST internal battery life is longer than quoted above. TST advertises internal sensor battery life as “up to 4 years”. I have had them on both the LD and the CR-V for 4 years so far.
After using the flow-through style for 5 years, I switched to internal when I replaced the LD tires. Advantages are 1) less chance of damage or theft, 2) less chance of air leakage, 3) more relevant temperature indication, 4) better wheel balancing. Disadvantage is battery life is shorter than tire life, incurring expense of changeout of sensors during tire lifetime.
The external sensor vulnerability I experienced twice on the CR-V, one of which was probably from a drive-through car wash.

Our Doran RV 360 TPMS was installed in March of 2013 after a March Morro Bay GTG attendee had his toad's front brake seize, causing a fire that turned his prized Saturn into a puddle of melted plastic.
We were leaving soon on a long trip and having a TPMS seemed like a good idea.
Out of the original 10 sensors, a couple of them are still working on their original batteries. Our LD has a TPMS repeater mounted near the rear of the coach.

the TST non-flow through sensors just screw on the end of your Borg stems.  However you will probably have to trim out a larger opening in the rear wheel covers where the inside tire valve stem is located to make room for the sensor access. (See photos)
This can be easily done with avaition left & right tin snips.

Steve and Jill,

I had to trim the rear wheel simulators when I installed the Borg extended valve stems.  I used a Dremel tool and only had to make a notch for the valve stems to clear the simulators.  The front wheel simulators didn’t need any trimming.  The TST sensors went on without any further modifications to the wheel simulators.  Your LD is older than mine so there may be a difference in trimming the wheel simulators.

The first pic is the front wheel with the TST sensor and the next two pics are the rear wheel with the TST sensors.

-While not the fastest method, a Dremel used with sanding drums is a clean way to open the valve-stem holes.
-A pneumatic die grinder, with a carbide burr, will quickly remove the excess stainless steel. It's easy to remove too much and it leaves sharp edges that need to be sanded smooth..
-Tin snips are hard to cut clean, well-rounded holes.
-A sheet metal nibbler can be used.

-I have seen plasma cutters used, mainly with less-than-pleasing results.
