replaced the bunks last weekend.... I had made the new ones at home, (UV resistant outdoor carpet remnant from Lowes..../lumber/fasteners/waterproof spray glue....about 65.00.) I took em with me to the lake. I used my mini generator and it only took about 20 min to replace them. It only took about 30 seconds to remove the old ones.....all the fasteners were totally rusted out....I'm surprised they had not floated out.
