best material for new bunks

[Utahboatnut]

I need to replace the bunk boards on my trailer, the 2 long ones are pretty bad, the 2 short ones are pretty good. I'm going to do all of them just because what do most people use? Treated, painted or stained fir, I have stainless staples for the new carpet. This is for a 20' crownline with a 350 merc. I also plan on having them all made up with carrige bolts pre sunk 1/2" or so and a extra disc of carpet on top of bolt head under carpet that wraps them. Then I can just drop them on after I remove the old ones while at the lake. What material do most of you use and does this plan sound okay? Thanks for any input on this.

Cedar holds up well, and the carriage bolt heads can be a mother to get out once the new bunks rot. Some lag the bunks on from below. Use nylock nuts to secure the bolts if you go that route.
