On my all aluminum utility trailer, I used inexpensive pine -- 2x4 for the
"stakes" and the bottom rail, 1x4 for the rest of the side rails. As for
treated wood -- I wanted to use it but there was a caveat on the wood that
it was not meant for prolonged contact with aluminum. So I just slapped
some Minwax polyurethane on the pine. Been there for 2 1/2 years and still
OK.

Wanting to construct wooden sides for a 6 x 12 flat deck trailer.
Trailer has stake pockets to accomodate 2 x 4. Using this for
construction debris, mulch, trips to dump. Of those that have
constructed similar siding, what spec of lumber have you use and found
works or (perhaps) did not? Was considering 2x4 verticals with 2 x 6
or 2 x 10 horizontals, but perhaps the 2x horizontals are overkill?
I've had some suggest lighter weight 1 x 6. Ditto suggestions for
pressure treated wood. thanks
