Okay guys i have 154,000 miles on truck, the last couple weeks at times the starter seems to be dragging to start. And it take a couple starts to get it going, all battery posts are clean and tight. Both batteries have been tested a couple times and is 12.80 volts. At startup the voltage drops to about 10.50 volts. Is the started on its way out are i need to check something else on truck.
