Thanks for the advice guys. Got the batteries swapped out and now I'll be shopping for alternator! I did get lucky these ohio hi way are dark as hell midnight! Had the lights on just low beams and radio.
Got off work last night and my battery light was on only had about 10 volts (one tick before the orange area on the voltage gauge). Had the truck doing 70 to get home fast as possible. It shifted good but my tach wasnt working and the battery light was on the whole time. God was on my side...
