Ray,
I also use the Pressure Pro which is very similar to the Dorian. They have performed flawlessly for more than 2 years now. I have removed them several times for routine airups, tire changes, etc and they reseal with no problems. Battery life can be prolonged by unplugging the controller unit when the bus is not being used.
When installing or removing, one has to be careful not to overtighten. That said, I use a 1" six point socket with an extension only (no handle or ratchet) on the inner dual to obtain finger-tight torque. All other sensors are finger tightened.

Ray,Both of my coaches had a 6 inch extender with a rubber gromet from Alcoa that stabilizes the extension.I have not had a pressure pro sensor leak but I have replaced a extension.

I'm just curious....why can't these tire pressure monitors be used with Equal? I have tried to find anything in the literature on line that says its use is prohibited and can't find anything.
The reason I ask is if that is the case the true cost of a system then must include Centramatics or their equvalent, right? I'm not opposed to either because there is way too much evidence that both have done a great job. But I still struggle with external sensors and the fact that you rely on that single seal, and you have the extra weight spinning around on the valve stems.
How do you remove the inward facing sensors from the outer drive wheel?
-
inward facing stems
Loosen the nut around the stem and spin the stem around to a desirable position.
Right or wrong that is the way I dealt with it.

Tire Safeguard that is what I am switching to I went into detail in post 44 of this thread. I currently have pressure pro. Jon has a decent point about acess.
This product adresses all the issues and if correctly installed will provide reliable trouble free service.
How about it Will how is yours working

I use a 180 degree extender on the outside dual,it will tighten and will not rotate,the one that I bought is made out of stainless tubing.

I'm curious about different pressure values for different axles. In my previous coach, following Michelin guidelines, I ran something like 125, 110, 95 in my front, drive and tag axles.
In looking at the documentation for the TireSafeGuard unit, there is a single low pressure warning level. Given my pressures from above, my tag axle is already 30 pounds under pressure.
How is this handled?
On the Smartire unit, and I believe the new Dorian unit (360RV), I believe these are independently settable per axle, if not per wheel.
Thanks,
Ray

When you screw your sensor in any particular tire the pressure is senses is that tires baseline and if it goes down 10%n the alarm goes off. If you have 100 in the tire it goes off at 90. If your tire is inflated to 80 it goes off at 72.
They advertise twice the battery life at half the cost of pressure pro. You can air through them and I like the mounts on two opposing studs connecting the sensor to the valve stem with flexible tubing.
Jack yes there are stainless valve stems.
Jon many many truckers are safely and reliably using these flexible tubings attatched to the valve stems. Many go to a cats eye that equalizes the pressure in the duels. The flex tube is attatched half way down with a bracket and the 2 sensors attatch to opposing wheel studs with little disruption to balance.
Take the savings and get the ballance rings.

I called the TireSafeGuard guys and left a message. Steve Wong called me later this evening. He indicated that indeed pressures can be set per axle, but he indicated the manuals on the website were out-of-date, and wouldn't show that.
He promised to email me newer manuals, but as yet I haven't received them. Maybe tomorrow. I was more specifically asking about in-tire monitors, rather than the screw on. He did indicate you can mix and match however. For example, I'm thinking I would want in-tire on the bus, but screw-on for my toad.
Still haven't made a final decision yet.
Ray
