From what I can tell, the 3100 Canopy Express in the 47-55 years had the plywood floors and the 3800 had the plank floors. I suspect that the panels were the same way.
I feel better now that I'm getting some reinforcement of my plan. I'll have both sides out of the truck and I can drill out the spot welds.
I hope I live long enough to finish this project. I'm 63 now.
I'll post some photos in a day or two.
