Was doing a little boat maintenance this weekend and noticed some of the carpet a little loose from one of the bunks. After looking a little closer the bunk is in rough shape. Wood is starting to rot and the end is broken some. My trailer is only 4 years old and is always stored in my garage and still the bunk is going to pot rather soon. I'll know when I take them off but they appear to be treated lumber but not 100% sure. Bought new lumber, stainless steel lags, stainless steel staples and bunk carpet ready to make some new ones this weekend. Just keep an eye on yours before they rot completely away.
