Just recieved my Doran 360 and installed it (Happy Father's Day to myself!). Didn't realize that the regular pressure guage I was using could be that far off at the supposedly same readings. I like the fact that the memory of the sensor will not change if you take it off of the valve stem. Will put it to the test in about a week or so when we leave for the Badlands. It has temperature set point but it is at a level that I believe that it would be way too late to do anything about saving the condition of the tire. Good luck!

That's odd, my Doran 360RV does not monitor temperature. Do you have the 360HD system?
The HD system online brochure and online user manual do not mention temperature alarms at all, only the general info page for the HD system says anything about a high temperature warning being included. **** Edit: I brought this fact to their attention. She said that she would have someone look into the matter. So, I think that statement will soon be addressed and maybe edited out of their web page. End edit ****
Hmmm, now you have me wondering! If there is indeed a temperature feature, I may have to see about them upgrading me to an HD system. If the high temp feature is just an interpolation of pressure increase over a period of time and not an actual temperature reading, then they can keep it. I guess I will call them for more clarification on the matter.
**** Edit: OK, I called Doran and confirmed that neither the RV or HD system has temperature monitoring. The only difference between the RV and HD systems is that the HD monitor has different software/firmware for truck fleet management purposes, such as more sensor positions, un-editable time stamped alarm logs to keep truck drivers from manipulating alarm info, etc., stuff designed more for trucking companies. The sensors themselves, are exactly the same. So, I guess that I will be keeping my 360RV system after all. End edit ****
The 360RV does have a high pressure alarm which is 25% over the set baseline pressure for each position. So a tire's baseline pressure of 80 psi would alarm out at 100 psi, a baseline of 70 psi would be alarmed at 87.5 psi, a baseline of 60 psi would trigger at 75 psi, etc. Hopefully, when the tire heats up excessively, the pressure goes over the 25% mark before a blowout occurs. It is a weak point of the 360RV system, I think. That being said, I still chose the Doran 360RV TPMS over several others. One thing that I do like is the fast leak alarm, which goes off if the tire loses over 2.8 psi within 12 seconds.
Also, I do not think that the 360RV sensors themselves have any memory at all, they only send pressure info to the receiver/monitor unit, which has all of the stored memory and functions. Are the HD sensors different?
**** Edit: No, they are not any different. End edit ****
If you have an old school, sliding stick, tire pressure guage, get rid of it. Get yourself a quality dial type gauge, or at least a digital one.
