Aftermarket tire pressure monitoring system.

I put this kit on my camper about 6 years ago. I've had to replace the batteries only once so far. The receiver part that goes in your truck is solar powered. I leave it in the corner of my dash year round, even when I'm not towing and it has never needed to be plugged in, the battery stays charged from the solar part.

I'm not a huge fan of having the sensors hang off my valve stems, but so far so good. Although, it is a little cumbersome removing them when I do have to add air. I think when I get new tires this summer, I am going to look at sensors that mount internally.
