Yes, Ranger and Explorer were both packages on the Full Size Pickups.
We had a 73 F-250 Explorer, I was s 2wd Regular Cab Long Bed, had a 390/C6, Had a cloth seat a stripe along the rockers, factory a/c front bumper guards, rear step bumper, the large mirrors, not towing mirrors, bur they were nice sized mirrors, the bedside tool box and the rubber molding inside the dent (what makes them a dentside). Not sure what the package brought, but for a 73 it was fairly nicely equipped.
