Hi All,

I have a question. Recently I bought a metal frame / axel that serves as
the
base for a trailer. All I have to do is put on a floor and sides.

I plan to use plywood for the floor and sides, with 2x4's for bracing the
sides and corners. I plan to paint everything, top and bottom prior to
bolting it to the trailer. When not in use the trailer will sit outside.
No
room in the carport .

My question: Since I plan on painting, do I need to go to the extra
expense
of purchasing pressure treated lumber, or will standard lumber hold up
fine
since it will be painted?

I'd appreciate any suggestions, especially from those who have done
something similar.

If the wooden portions will be in contact with the bottom of the trailer,
unless you're hanging it up, go PT on them. Leaving them outside in the
rain will collect water between the bed and the sides, rotting them out. PT
ply makes good sense for the same reason. Anything you leave in the bed
becomes a source for hidden water in that case. Where drainage is
guaranteed, regular is dandy.

I lucked out with my "anything" hauler. Was up servicing a site one day
when they took down the old microwave reflector. Bottom of my trailer is
6x8 of well-braced aluminum. Thing fit within a half inch all around.
