Frank,
I would highly recommend PressurePro!
Two years ago when we were leaving old Mexico after spending the winter, we nearly lost one of our dual wheels. By chance we stopped at a roadside vendor and then noticed the wheel sitting at a peculiar angle, held on by one lugnut. The tire was flat, but fortunately not ruined and we were able to get it aired up and using one lugnut from each of the other wheels, and with help from a friend following us, put the wheel back on our motor home. What amazed us was we had no indication riding inside the motor home, that there was any problem with the wheel.
When I returned home I began to look for a TPMS and did a lot of research. My conclusion was that PressurePro was the best. PressurePro is the original TPMS having been in business 19 years. The system is very user friendly - easily installs in 20-30 minutes; monitors tire pressures 12,343 times every 24 hrs, alerts you to a problem before it becomes serious with a visiual and audible alert to 12 1/2% loss in pressure and again when 25% pressure is lost. PressurePro is the onlyTPMS made in the USA.
I told one of my sons about it, who bought a system for his 5th wheel, and four RV friends of the benefits of the PressurePro system and they all purchased their systems from the dealer where I purchased mine. My wife told me if I was going to keep "selling" the product, I needed to become a dealer. So I did. All my customers seem to be happy with the system and I haven't received any complaints.
Also, when removing the sensor to put more air in the tire, it is not necessary to re-program it. Just leave the sensor off for 60 seconds, replace it, and it will automatically use the new pressure as its baseline.
Happy trails,
Larry
