I tow a loader flatbed trailer with our "C". One day I got the trailer out and checked the tires with a tire pressure gage, they were fine, I loaded the trailer and also the mh. About 4 hours we were all loaded up and left home. About 20 minutes later we stopped so my wife could get a few things she needed. While she was shopping I did a quick check of the trailer and load. I found that the trailer had a very soft tire. Checking the tires with a pressure gage had caused the valve to start leaking.
Now I carry a radiant temperature sensor to check tires whenever we stop for a short break.
