I have a brand new, in the box, never used, 25' 50 Amp Marinco power cord and also the inlet box with the 'Twist Lock' feature. I decided after purchasing it that we would not convert the Barth to 50 Amp Service. If there is any interest here, I'll sell it for $325 plus shipping which should save somebody some money. Retail is about $400 Otherwise, I'll return it to the place I bought it from
