Special-k, this pic really brings back memories for me. My current 68, was my dad's truck, and it had a cover on it. Except for the fact that your's is a GMC, it could have been mine before I restored it. I have been toying with the idea of finding a camper cover of that style to put on mine, just to really make it look like it did in the day.
My dad bought the truck when I was 5 years old, and I remember standing in the bed, and my head not touching the roof of the camper.
Here's mine, just for comparison.
