Trailer deck replacement

[Machias]

I have a 16 foot flatbed trailer.  I need to replace all the wood.  It had plywood on it.  The support beams run lengthwise.  What wood would you all recommend?  Thanks!!

Lengthwise over 16' is tough with any kind of lumber, and very expensive. You don't want to run planks across the width if you plan on shoveling any kind of dirt/mulch, etc... out of it, that's just a shovel catcher. You may be best off going back to some 3/4" plywood.

Edit, you said flatbed, not utility. You mainly hauling small machinery on it?

If it's lengthwise I might just go back to a plywood and use an outdoor primer on both sides and ends before install.

Support beams lengthwise and nothing running across from one side to the other???

Yep, I'll post a photo of it shortly with the wood removed.

I have hauled all kinds of stuff with it, but it will be mainly used for hauling around a couple of catarafts from now on.

Which plywood would you guys use?

If plywood I would go 1-1/8" T & G.
Never know when you might wanna haul a whole moose on it.

I would use 3/4 CDX painted or polyurethane.

Yup.
For that trailer 3/4" CDX would do the trick.
Tongue and groove joints would keep all seams the same elevation and provide strength at the seams.
Good Luck.

And not allow water to drain
