For Sale - 50 ft. Marinco 250 / 125 V 50 amp shore cord. This was my back up cord when I needed extra length. Brand new female connector plug (old plug was starting to separate)shorecord.jpg. Asking $250 plus shipping. I live in Nevada near Lake Tahoe and this cord weighs 44 lbs so shipping to the South or East coast may be costly, estimated shipping to West coast is approximately $40 to $45.
