We have been using the Pressure Pro for a couple of years now and the system has done a great job for us. Finger tight seems to work very well along with a soap check. Our seals are the red color and are very soft. Would surmise that seal problems could be due to nicks in the stem.

For those who are concerned about temperature sensing, Joe's comment about increased pressure due to his generator exhaust illustrates the fact that high temperature is indirectly sensed by the system. When pressure decreases or increases more than about 12% the offending wheel indicator flashes and you will experience a very noisy pressure alarm.

As to dealers, there are a number of small dealerships around the country. We purchased ours from Mike & Pat McFall (850-294-0281)who sell the Pressure Pro at numerous RV shows etc around the Southwest. I believe they winter in the Wickenburg, AZ area.
