I guess my point is that you shouldn't worry about what your truck looks like or what others might think of it. I was a little diffident about Ol' Roy at first because it is in no way cosmetically up to snuff compared to my other vehicles. I got over that.
Believe me, people will be thrilled to see your 80 year old truck driving around town in any condition and aren't going to give a hoot about or even notice the plywood bed. They'll be amazed that they actually encountered a truck that was built in the WWII era driving under its own power.
The average guy on the street is more forgiving than armchair quarterbacks and know-it-alls at car shows.
The only opinion about your truck that matters is your own.
