Well, you can use regular 2x4 if you're that environmentally conscious, but it won't last very long. You'll probably end up replacing again in a couple years. The pressure treated is more water resistant. I'm assuming you have the "wishbone" bunk trailer with curved bunks. I don't think the cut angle is critical but it's close to 45 degrees. When I replaced the bunks on my '79 CC trailer I just eyeballed the cuts and blasted away with a circular saw.. No worries and you couldn't even tell once I recarpeted it. Getting the curve of the trailer wasn't difficult, either. Just work your way down with the through-bolts bending as you go. Cake...
