Fleetside wood bed question

[fun in dirt]

You can do it, but run a risk of bending the lips on the panels that the wood sits above/below if they are not evenly supported. The wood floor is 3/4" thick & sits on top of the front panel bottom lip & under the bed side lips. You could get a few 1x2 boards to place along edges and make it work, and then run a couple of small ratchet straps across, hooked in stake pockets for more support, especially if missing the tailgate.
