A truck that will not crank is often the fastest roadside fix there is. RIG dispatches a mechanic with heavy-duty jump equipment and replacement batteries.
Beyond the jump itself, the mechanic tests the batteries and charging system so you do not end up stranded again at the next stop — and replaces batteries on site if they are done.
Almost always a complete roadside fix. If the alternator itself has failed, many can still be replaced on site depending on the engine — dispatch will set expectations before anyone rolls.
RIG works on anything diesel — and only diesel. Big rigs and semi trucks, diesel RVs and motorhomes, diesel pickups and work trucks: every mechanic in the network is a diesel mechanic, so your breakdown goes to someone who works on engines like yours every day.
