One of my classmates at Navy Nuke school had an F250 of this vintage that he put a cap on. Together we altered a cover from an old liberty boat to cover the bed on my 67 GMC and my first camper was born. I don't have any pics because cameras hadn't been invented yet :)
On weekends, we traveled up and down the Sierra Nevadas and then the western Rockies when we transferred to Idaho. Some good times. It's funny how seeing an old truck can bring them back.
