So i just came back from a trip..... From Colorado Springs, CO to the Ozarks (Missouri)...... Trip was 800 Miles one way 1600 round trip........ I am at 43500ish....... So earlier today my Maint light started flashing upon start up...... So here is my question !!! What is that Maint light Hardwired to............. I know that i have to do some work on my truck already...... But could it just be that i have to change my oil ? Or could it be something major ? I change my oil every 5000 miles as per the Maint Guide......The truck drives like always, Great ! But wondering why dis damn light went off....
