Question for the guru's. Been noticing when starting truck for a brief period the display says check brake system. Happens on and off. last couple of times now the speedo pegs itself and drops back down. Well tonight truck would not start. Cranked for about 3-4 seconds then went south, i mean south. batteries are dead. Is it worth taking batteries out and having them checked? Truck has 13 some k miles on it. It sits the majority of time in garage since I bought the truck mainly for pullin our toy hauler. Anybody think they might have any insight that would help? All stock except Edge Insight.
