On the side of my '06 Freightliner Columbia, is the standard 110 VAC plug-in. Is this plug for charging the onboard batteries or just for the engine block heater...or both?
This may seem like a fairly silly question, but I am just not sure. I have never had to plug in at night as my tractor has always been kept indoors.
My new house has over 40 acres and I am now keeping my equipment at home with all the room.
