Several years ago, I had a Ranger pickup that needed a few enhancements. Due to the nature of my job, I had limited access to the shop so I wound up doing it in stages:
One of the first things I did was ditch the rear bumper in favor of a roll pan. Instead of going with metal however, I chose some 100 year old oak that had been salvaged from a church. Gave it several coats of marine urethane, added some aluminum trim (painted to match the truck) across the bottom, and mounted it up.
Next on the list was the inside of the cap. Along with the false floor, I lined the inside of the cap with fabric and trimmed it with oak. Two additional pieces of oak mounted just above the side windows provided a convenient place to temporarily store the floor panels when needed.
Kept the ‘oak thing’ going underneath the false floor by making some panels for the sides and across the front.
I didn’t stop there however, because a few more items needed a home to make the transformation complete. The video below shows where those items lived.
