    For you guys that have dash cams, ScanGuages, etc. that display it, what is your average battery voltage on your 2nd Gen? I am showing an average of 13.3

    My other Toyota's, two 4runners and my Hyundai always show 14v. The only time I see 14v on my Tundra is when it is extremely cold outside. As soon as it warms up it drops to about 13.5v.
