x2 on the TPMS! We wouldn't think of leaving on even a short trip without our TST-507 up and running. You can check pressures when hooking up for the day's drive and then run over a nail on the way out of the campground gate. The TPMS will alert you something is wrong or a tire is losing pressure. They aren't cheap, but then neither is a new tire, rim, wheel well liner, fender trim, and possibly a wreck.

"Happiness? A good meal, a good cigar and a good woman - or a bad woman; it depends on how much happiness you can handle."
George Burns (1896 – 1996)
