I've got the old fashioned gauge I bought at a truck stop. Had to buy it because trailer tires were low and my digital gauge had quit. Not going to count on digital gauges any more.
I knew the trailer tires were low because of my tst. We were pulling the trailer in to go to florida, it had sat at my work campground for over a year. The air compressor I have kept with me for years wouldn't put enough air in the trailer tires so had to slowly make my way to truck stop.

I mainly count on the tst for trailer and the dash for my ram dually tires.
