Wheelhouse flooring

[FishHawk11]

Curious what you guys have been doing while laying the subfloor. 5/8" or 3/4" . Can you just glue it with construction adhesive or should I screw it with self tappers or both? Got the frame covered in truck bed liner tonight and hoping to get the flooring down tomorrow, Thanks for the input.

Depends on what is underneath.

Is this going to be spanning the framing, sitting on insulation, etc?

If its going right on the frame and going to be spray insulated after, I'd go 3/4.

I to have a bedliner frame just put floor down 2 weeks ago, I used 23/32nds treated lumber and glued everywhere that contacted the frame all my frame bracing is 2 feet on center so all my boards were 4 feet butting against each other on the center of the trailer bracing. I used 1 7/16ths texs self tappers with specific coating used to screw lumber to metal. All worked awsome id do it again all the same way.
