>>840702Call the mechanics and take a nap while waiting for a fresh one. A year or two ago it happened to me and I fell asleep in my truck. The battery box is right under the driver's door and I woke up to the mechanic wrenching on shit.
These trucks only have 2 big batteries since I don't run a liftgate or a bunch of accessorie but most semi trucks will have 3 or 4 batteries, especially the sleeper cabs.
