What are you asking exactly?
Difficulty in installing the oak strips? alternatives to boards?
I used 5/8 plywood because I was missing the rail strips. came out
ok I think.
Obviously I still need to finish it with a cap on the end. (I also left the plywood out too long before I used it for this project, hence the slight bowing)
There are people that have used Trex Decking boards, and some that have gone with steel floors from the 75-87 trucks.
It al depends on your resources and the time you want to invest.
