Redecking a flatbed, what should I use?

Am I the only one that keeps reading the title as Red Necking a flatbed.....

 

White oak doesn't shrink much when drying. A 6" board usually loses about 1/8" width going from "don't know its dead" green to 8% (dry).
Keep fasteners towards the center of the board, orient growth rings properly and it'll dry better on that trailer than it will in any kiln.
And, it'll stay slip resistant!
Best way to anti slip wood is to scuff it... Wire brush or flap wheel on a grinder makes fairly short work of it, or a floor sander (rent it from depot)
Sand across the grain for anti slip, or diagonally, creating criss cross pattern.

 

No your not the only one I read it that way too...

 

Thought plywood on the trailer was the red neck part.

 

I know that we have used a jack to push semi-green white oak in before, when it dries there will be cracks wide enough for a chain to fall through.

 

I'm sorry you had that experience.
I know urban /yard trees will do that, and if the trees were felled on the falling moon, they'll get ugly too... Had something to do with the sap rising and falling based on moon cycle...
Chestnut oak will crack and split badly, and is often sold as white oak... Pin oak too.
True white oak generally holds well and resists cracking and splitting pretty well
Narrower boards will always hold up better than wider ones
Rift sawn and quarter sawn are the most stable, plain sawn and boards with pith are the worst.

 

I’m not talking about the boards cracking, I’m talking about cracks between boards.

None of the big mills around here quarter saw anything. I know a couple of people running small band mills that will quartet saw, but it’s hard to get them to do it.

 

Apitong only way to go.
Predrill it. Self drill screws won't hold up to Apitong. It's like steel. I redid my drop deck... trust me on that. Use a 1/2" drill, too. A standard 3/8" drill isn't tough enough.

 

Correction use a "Good Quality" 1/2" drill... Black and Decker will fall apart before it even gets to the job...

 

How about some 10”x12”x4’
And some 6x8x4
