Have been looking for TPMS for coach and toad, so many systems out there and so many reviews, Just want a system that's easy to install, good monitor and does the job. Most of the forum reviews are pretty old and the systems today are much improved. TST, Pressure Pro and Tire minder seem to be the favorites, all are good. Any thoughts or opinions are appreciated.

The first system we used was a Tire Sentry (which is NLA) We have a TST now and it works as advertised.

Pressure Pro with their new monitor is the best, as it is checking tires every so often 24/7 alerting to sensor theft & tire problem even when parked. Don' think any of the 'others' have this feature, to reduce sensor battery drain. But Pressure Pro is the most expensive.
The thing I don't like about pressure pro is when the sensor battery goes dead
you have to buy new sensors unless they have changed it in the newer models.
Another Pressure Pro fan here. I went through two other before I settled on PP.
I have the Tire Minder A1As system and love it. It's been flawless since I installed in 2 months and 2 trips ago. I like that you can see the pressures of ALL tires on one screen all at the same time (no scrolling), and push one button and you see all the temps. It's completely wireless and comes with a nice AC or DC charger setup. Also includes two batteries for each transmitter (1 + spare).
Ebay had the best price. Here's the one I got with 10 transmitters (although I will need 2 more when I buy a trailer). These are cap sensors.

Same system I have been using and am very happy with it. The temp monitor let me know when a front caliper was hanging up before any damage was done.
Very happy with our TST. haven't had any issues.
The TST is great. But it is ponderous to set up. I think that for $450 the sensors included should at least be coded and numbered in the system. Then all you need to do is set pressure/temp parameters.
Pressure Pro here. Has worked very well.
We have a TST and it works fine, does exactly what it is supposed to so. Most folks like what they have nd if they have not had more than one system it is hard to say one is better than another.
TST customer service is great. They have newer sensors now with batteries that last 4 years with a guarantee. You can get they where you change the batteries (about once a year) but they have a somewhat limited life. After 8 years we may have one or two of the original ones.
I am slowly switching to the cap sensors (as opposed to flow through). If you need to air up your tires to max for a few months of winter storage it is much faster to remove the sensor and fill the tire directly than with a flow through. Just a preference.

I was just admiring a friends tire system because of that option. ( flow through ) maybe now, not so much.
In going from Oregon to Arizona to Texas pressures change. How do truckers do it ?
Maybe that's why truck stops have those "auto fill" stations for air ??
Nope, still the same. Just bought 8 new sensors a few months ago.
Having owned several trucks over a 10 year period. The old country song lyric, 'We've got a long way to go and a short time to get there' comes to mind. When I owned my trucks TMPS wasn't a thing. So a weekly or more often pressure check was the standard. And it worked.
I drove 1.3 million miles in my non-TPMS equipped trucks checking tire pressure once or twice a week and never gave a passing thought about corner weighting, barometric pressure, Road surface, sun angle Etc. I pulled two trailers and was always at 75MPH. I had ZERO tire failures in all those miles.
We RV owners however have nothing but time and we use that time to (at times) study then over think about the barometric pressure, Sun angle, corner weighting and the effects those have on our tires. Which from a scientific stand point are of course very valid. But in real world driving less so.
The one thing I do not like about TPMS. I look at the damned thing to much while driving. I'm thinking about tilting it's display down and just lifting it to view it 'every now and then'
The one I have turns off until it sees a problem. You can wake it up with your finger if you want to check pressures.
I like that craneman. I may have to do a deep dive on the TST and see if that might be an option. Although I'm sure it doesn't have that.
I have the TST and it's a pain to learn the language it needs to set up, but does work as advertised and I do like seeing the temperature. Personally I would prefer internal sensors that would last tire life but aren't within my price range. I agree 100% you have to spend too much time waiting for it to scroll thru checking all the tires one at a time. Keith's tire minder looks quite nice except I don't see the temp displayed and do think knowing what brakes and wheel bearings are doing is equally important too me. I have personally had more tire leak issues with the caps than I ever did with proper metal valve caps and closed valve stems. By installing the pressure cap sensors you have deleted 1/2 of the sealing devices by holding the valve stem open. I also have issues with the added weight of the pass threw sensors hanging on the valve stem. I guess I'm still in the learning curve for what I want. I do however like knowing what's going on.

Due to our brass valve stems being screwed to the wheel and rubber grommets to support the inner valve stem as it passes the outer wheel. The weight of the sensor is a non-issue.
The Tire Minder display shows all the pressures at once. If you want to see temps, you press a button to switch to all the temps instead. Press the button again returns you to the pressures. I figure if the temp is going up, then the pressure will be as well, and I can swap screens to see what's going on.
No leaks so far with the caps. I've actually had to take pressure out as our ambient temps are going up.
See this video. At about 7:15 in, it talks about baselines and how the A1As alerts based on these. At 10:25 they show swapping from PSI to temp and back again.

Here's how the alerts work:

Newer model than mine. More features but mine still does the basics, temp and pressure.
I like my pressure pro pulse FX system. The black box hears all RV and car sensors from a central location in a bay, and communicates with a app on my iPhone. I check my pressures every morning without needing to move.
I have the TST system. It works fine, unless you decide to use the security nut that comes with the sensors. If you install the security nut, it will be a pain to remove if you ever need to. I installed it and now that it is time to replace the tires, it was difficult to remove the nut. So I will be reinstalling without the nut.
I'm looking for a 12 position monitoring system. I would like a visual and audio alert.
I don't want cheap.
We got a tire-safeguard system several years ago from Dion Elrod with HCI Corp. His number is 562-926-7123. Don't know if it was cheap or not. When ever I had a question about what it was doing, he could always straighten me out.....that's worth something.
Ernie, we like our TST system and it can cover all 12 plus some! Gives us the temps as well as the air in the tires! Hope this helps.
Many have and use this system!
I have the Tire Minder A1As. I believe that it will do 23 tires total. You can assign trailers and "disconnect" and "reconnect" as you need them. You see all tire pressures on one screen at one time (no scrolling). Same for temps at one touch of the button. It alerts for over temp, over pressure, under pressure, slow or fast leak. I'm happy with it.
It does up to 22 tires and has all the features you mention.
I have a Tire Minder also and it will also go up to 22 tires. Mine works in conjunction with
a smart phone. It came with the coach and also a pressure pro came with it but all the sensor batteries
were dead and with that system I would need to buy all new sensors as the batteries in the
Pressure pro aren't changeable.
Ernie,
I switched from Tire Minder to TST and I am glad I did.
I bought mine here: Tire Safety and TPMS | TST Tire Pressure Monitors | TechnoRV (https://www.technorv.com/tst-tire-pressure-monitoring-systems/)
TST with 12 cap sensors.
TST for us too. I am slowly switching to cap sensors from flow through sensors. TST just came out with a glare shade, works well.
TST for us too.
Sounds like a good concensus
Another vote for TST, with flow thru sensors.
I was going to stay quiet about sensors but since it's been brought up I'll put my two cents in.
1. #1 source for tire leaks for me has been sensors. Screw on external caps
2. Flow threw makes sense but I don't like the idea of being external, screwed on, more weight on the stem.
3. Loss of secondary sealing
A. Carry spare sealing orings
B. Recommend installing tight with supplied wrenches and lock nuts
C. Have someone show you how to program location and display position
Note, separate rear axle to near the end on the tow vehicle display. Looks more normal
4. Internal sensors batteries are not changeable and you must replace sensor every 5-10 years.
A. Would be my first choice
B. Would retain secondary sealing
C. Cost too much
D. More difficult to install but proven to work better in everyday operation

Pressure Pro Pulse, that it, the only one. . .
And it may be the only TPMS to report pressure & changes while stationary.
The Tire Minder A1As is active at all times, moving or stationary.

Read the instructions, it goes to sleep when no motion is detected. It fooled me because it showed pressure the next morning and I thought it was my actual pressure. You have to push the middle button and the right button and hold until it zero's out then it will give the new pressures after it reads the sensors again.
Sounds reasonable. When I get to my camp spot, I turn the monitor off. Fire it back up to check pressures or before I leave. I've never left it on overnight or when not driving as it's battery powered/rechargeable, so I didn't want it just sitting on, running the battery down, while not being used.
When you fire it back up it is showing the last pressures before the coach stopped. Check the numbers next time then reset it and see what the current pressures are. I turn mine off when I park also.
I usually leave our TST on overnight if we are on the road or turn it on a couple days before we leave if we have been somewhere for a while. TST works whether wheels are turning or not. I want to know if I have a low tire before it is time to leave.
The TST has the advantage of not having to reset the Tire Minder when you are getting ready to leave. The Tire Minders advantage points are it goes to sleep while you are driving so as not to have you keep looking at it. It wakes up if there is a problem. Also Tire Minder advantage is $5.00 to get a full set of batteries and o rings once a year. The negative on my Tire Minder is the high and low pressures are not programable you set the cold temp pressure and it uses a percentage for the low and high warnings and the TST lets you set the high and low pressures and the high temp that you want. Other than the color monitor option for the TST they are very much the same.
I have been using TST since it first came out. Started with Pickup and travel trailer and moved it to the Foretravel and TOAD last year. Started when TST had non changeable batteries. Now using sensors with changeable batteries. It is a great system and has saved me many times.
Pressure Pro sensors never sleep. They transmit psi every quite often and if psi drops suddenly, it instantly transmits, which is also an instant warning if someone unscrews a sensor to steal it.
We are now stopped in a campground for many months. Dash monitor is always on and when I think about it a couple of time a week, I look at monitor to see current psi on both axles. Also nice to know about slow leaks long before we are ready to drive.
I am not aware of any other TPMS that can offer the above features.
My TST does just as Barry described. I let some air out of the rear tires yesterday and it went off when i removed the sensors. Ours is on almost all the time. A slow leak or fast change will set the alarms. You can set high and low pressures and temps. It will go for a day or more on batteries but it normally is just plugged into a USB charge port.
They all have one feature or another that is nice. The main point is to have one to let you know if something is changing so you can do something before it is a bigger problem.
Roger, glad to hear that TST TPMS does not go to sleep, only to be waken by tire rotation. Good news. Thanks, Barry

I dont have a lot of spare cash . race car, race car etc.
This seems to work well and saved my but this past trip. I had a leaky stem gasket on the outer rear and this system showed it as well as audible. .
Gunna have to check my gauge to the system . Normally I set my gauge to my Chevy truck system . I have about a 5 psi delta at 85#.
I have the "Crossfire " on the duals I share the concern over the cap seals , but I check the pressures every roll.
