Not sure if it was exclusive to MN or not, but Ford had a Northland Edition F150. My 2000 was a Northland Edition, i think it came with a block heater and a decal. I know they made them in subsequent years from seeing them advertised, not sure if they currently do or not. Chevy has a Minnesota Bound edition which is an outdoors show in the state, which leads me to believe the editions are more of a marketing scheme by local dealer associations than anything else.
