I snapped a bunk over the weekend on a Lund Impact 1775 bunk trailer. They were the originals - never had been replaced in 8/9 years. Felt pretty soft like maybe it was rotten. I used the search feature here and found threads from a few years ago. What are the current trends on replacing bunks now?

I called my local marine service center. They use regular framing lumber to replace bunks. Not cypress, nothing treated, just regular ole' framing lumber. When I searched this on Google, I got a lot of different opinions. Perhaps the same here, that's why I'm asking.

Also, my current system has carriage bolts coming down through the top of the bunk (counter sunk). However, some use lag bolts from the bottom up when replacing. The difference here is that with lags, I can carpet the bunks in my shop, launch the boat and quickly replace the bunks - Vs if I use carriage bolts from the topside down, then I need to bolt the bunks on via a counter sink, then finish the carpet. I won't be wrapping the carpet all the way around bunk, to aid in drying of the wood.

Anyone using glue in addition to staples?
At this point, I'm not interested in the composite bunks that don't require carpet.

Thanks!

I replaced my bunks on a 2001 trailer 7 years ago. Used treated wood, glued the carpeting on top and stapled at the bottom(stainless). Used lag screws from bottom. Easy boat landing replacement and still holding up fine.
