Can this monitor simply replace the old one or does it require purchase of the entire package?

[Davy]

You can just buy the monitor, it works with your current sensors and repeater.

I’m trying to nail us down a PC price with my distributor, more to follow.

Great. I like my current model but find the monitor too large to mount without being obtrusive. The dimensions of the new monitor in addition to being more versatile, appears to be easier to locate and have better viewability. Looking forward to your review.

Questions from a naysayer:

Since using fill through valve stem caps my air loss in tires is approaching zero with seasonal adjustments being the primary reason to add air. How well do the sensors seal?

I have 3 toads, all take completely different tire pressures. What is involved in reprogramming the pressure for the toad sensors? How long does it take to program the sensors?

The monitor looks good.

Jon I have had three sensors fail and leak you can get new seals but I just bought new ones I do not have them anymore on this coach , I have fill through valve stem caps now and barely have to add air to the tires over the year . I run a little higher pressure than most ,so up and down 5 psi is no big deal to me , always more air than I need for weight of bus

[Davy]

I’ve
not had any loss of air from the sensors and do periodically check
them against a gauge.

The
beauty of the new monitor is for just the reason Jon mentioned,
multiple vehicles or towing options. It can monitor 5 different
vehicles and up to 80 tires from the single monitor. So now Jon can
put sensors on his bus, 50 Ford, Hummer and Dodge Pick-up and monitor
any or all. Seems like a good idea for someone that tows a trailer or
a toad, no more moving sensors around and reprogramming each time you
want to hit the road.

I
thought the temperature read out was a big plus as well.

I think the system is a must have for sure just have not got around to getting one, I pull a trailer all the time and it was nice to have it was on last coach , I would recommend everybody gets this system

[DON]

This may be a dumb question, but if this unit can monitor up to 80 tires or in Jon’s case, five vehicles, do you have to install sensors on all the TOAD vehicles and then you simply move the monitor from vehicle to vehicle?

Also, can a DIYer do this or is this a professional install?

If I can past this seal issue I may be a candidate.

A long time ago a company offered valve stem caps that showed a green band when the priessures in the tire were OK, but if they dropped the band was red. For any tire pressure monitoring system to work it has to release air pressure from the tire Schrader valve into the sensor. That means if the sensors do not seal perfectly the sensors become a leak source. On my very first trip with those sensors two leaked. Ever since I have been gun shy.

I have run with the fill thru valve stem caps for years now and those caps are literally a double seal. The Schrader valve is the primary seal as intended, but the cap also seals. I am struggling to accept the fact I would be putting a sensor on a wheel that has to have a perfect seal or it becomes the source of lost tire pressure.

Peter, how did the three leaks occur? Were the sensors cross threaded? Did the rubber seal fail?

Has anyone else had issues with leaks at the sensors?

I have carried around a set of Pressure pros for my coach and car, but like Jon am a little gun shy to use them. First I see no way to put them on without an extension, and the extra length with the monitor on the end I am afraid it might cause a leak, I had Smart tire on my two previous coaches, but do not like the band around the rim. maybe I am just a little too cautious, what are fill thru caps and can they leak? I thought when you put the valve cap back on it helped seal in case of a bad core? Gary

Jon the rubber seal inside sensor failed the sensors where not new I put new ones on and they where good for two years without trouble still going as far as I know

My procrastination regarding tire pressure monitoring has evidently paid off.

Looks like I can buy one monitor/display and enough of the little things that go on the tires for the toad and the race trailer and whether I’m pulling with the coach or the Suburban, I’ve got tire pressure and temp all covered. Just program the new fancy monitor correctdly and move it back and forth from coach to Suburban appropriately.

I’m wondering how one would fit a Silverleaf screen and the tire pressure monitoring screen an already full dash.

Peter, that’s the kind of info I need. It is entirely possible someone previously cross threaded a sensor or otherwise damaged a seal.

Anyone else care to share.

Keep in mind Tom needs the business so he can buy that slide coach and I am a ready willing buyer once I get past my concerns. Help out a fellow PC member

In late 2008, I bought the TST TPMS sensors for all the coach tires (8) and for the dingy (4) and a repeater antenna.

I never put more air in my tires than when I had those dang things on my tire stems. Two of the sensors went out and replaced by the manufacturer. I could never get the repeater antenna to work.

After several months of giving my pancake compressor the ‘Olympic’ workout…. I took off the sensors and sent them free to anyone who wanted them (a guy on rv.net took them). I wasted $599 on that system. After that, I just checked my tires before every departure. That worked until we sold the coach.

As you know, the new Liberty has a built-in sensor system that I really like. Also, it’s my understanding that TST is now making a system that goes inside the tire. Personally, I don’t want to attach anything else to my tire stems after my experience.

The sensor inside the tire/wheel is the only way I would go if I were buying again.

Safe travels,

Mark

On Edit: (after reading several posts below)…. The TST system that I purchased was rather new. They went through several improvements over the years. I’m sure ALL of those ‘spin-on’ sensors have improved greatly since my experience. And by the way, no one could have taken better care of those sensors than I did….. I pampered those babies… put a cot in the garage and slept with them.

I am excited to see how the factory Prevost one works out on the new Liberty. Those don’t have that pesky leak issue as they are mounted inside the wheel and don’t rely on the valve stem for anything. They also monitor heat, and do a pre-trip each time you start the coach.

From what I have heard, they are very nice and quite reliable.
