I was not in favor of purchasing our Pressure Pro system, didn't want to spend the money etc. Well, my husband, Cliff, talked me into it (glad he did). We used it on our F350 and fifth wheel camper. Boy, was I surprised and glad he did. On the second trip out after purchase it started to scream at us, letting us know we had a tire going down on the camper. We were able to safely pull off into a truck stop, called our road service and we were on our way in less than an hour. We sustained no damage to our rig. We now have it on our 2006 Fleetwood Excursion and on the trailer we pull behind our motorhome. The trailer is a combination of a swivel wheel trailer and a tow dolly, this allows us to pull our car and golf cart at the same time. Sensors are in place on the motorhome, tow dolly and car. I have to admit it gives me piece of mind and has saved our equipment and money using this great system.
