Hi guys! I as vacuuming today and when I pulled my floor mats out of my truck noticed a bit of mildew(mill-do)(idk how to spell that) on the bottom side of the driver side mat. So it would seem that it has been we for quite some time, and consistently wet. Then noticed the passenger side was also wet, just nothing growing under it. I have no idea why this could be so guys, why might both sides of my truck be wet('96 Z71)?
