You can get pressure treated but I would think just
regular garden variety 3/4" A/C would work just fine.

You could paint it or not....

The other choice is 5/4 decking boards which is a bigger
pain to install but will last three times longer.

The final and ultimate is PT 2x6 bolted on... they will
be there when the trailer is toast.
