    Question on bunk material

    Thinking about replacing my bunks. My plan is to purchase 2x4 pt and doing my bunks in the shop so that I can replace them at the boat ramp.
    My issue is most pressure treated lumber is not dry. I want to glue and staple the carpet but I don't see the glue working on wet pt.
    What's guys doing? letting the Pt dry for a while is my thought.

    2x6 pretreated are fine, staple only, no glue necessary. Replaced plenty over the years.
    My last set I went with Gatorbak bunk covers so my boat isn't sitting on wet carpet all the time which causes hull blisters.

    Mine are currently 2x4 not sure if can go 2x6 .
    I have also done a few and didn't use glue . I just thought I'd go the extra mile since I'm pre-making them. May just staple any way.

    Would definitely just wrap and staple them. A lot easier and they’ll hold up just fine.

    Pressure treated lumber is a no go if your hull is aluminum.

    ACQ (alpha copper quat or somesuch) is one of the three different treatments for pressure treated lumber currently (in the construction industry). It will damage untreated aluminum that it's in direct contact with. I've repaired decks with failed aluminum flashing that only lasted a couple of seasons. The flashing looked just like aluminum foil that had been in contact with a leftover lasagna for a few days - full of holes!

    1. this is with paper thin aluminum sheet flashing

    2. the flashing was sandwiched between pieces of treated lumber, not separated by carpet.

    3. ACQ is not the only available treatment (used to be very common/#1 after Copper arsenide was eliminated back in the early 2000s). The other two are not know to have the same issue.

    Thanks for the info. Glad I read this, I'm going to be replacing the bunks on my RT soon

    When you wrap them don't cover the bottoms with carpet so the wood is able to dry out quicker.

    I use pine and thompson's water sealer on my boat bunks. Not sure there is a different type of water sealer. I always replace new bunks with gatorbaks, so been doing this awhile and never had an issue with rot.

    Same boards on a Nitro trailer would need to be replaced in 2 years with my usage.

    After constantky wearing the carpet out I went Gatorback. Looks so much better, works good too.

    Why is pine better? I think I’ve always heard pressure treated also. I’ve never done it, but will have to eventually.

    After having Ultimate Bunk Boards on my pervious trailer I won't go back to carpet. Fixing to order a set to replace the carpeted bunks on my new trailer because carpet sucks. If you don't want slick bunks for easy loading and unloading that has its own set of risks because they're so slick I think Gatorbacks are the way to go.

    Never argue with an idiot. They will drag you down to their level and beat you with experience. Just smile and walk away.

    Was looking at the bunks on my Shorelander trailer last year, when i realized they are plastic (covered in carpet), so I guess I'll never have to worry about them rotting. Almost look like 2x4 plastic deck boards.

    No1 grade Southern yellow pine. Be selective of the board. No big knots, splits, etc.

    Would recommend switching to Gatorbaks instead of carpet, but if thats not in the budget be sure to use quality 316 stainless steel staples.

    I bought and renovated a dual axle to replace the single that came with my boat when I bought it. Everything I used to rebuild the trailer I bought at Lowes with the exception being the paint and decals.

    I used 2x4's that I treated with deck water treatment, then painted with bed liner, then covered with vinyl gutter material. The outer board are simply nylon garage door seals/ boards.

    When i load her up i just back it in to wet the boards then pull out to a proper loading position and she loads up dead center every time. it's been great so far and I don't anticipate ever having to replace a running board.
