I put new bunks on my trailer yesterday finally. When I went to tighten the lag bolts from the bottom they just kept turning...never really would get "tight". I predrilled just enough to let them get started, definitely not too big of hole. I put silicone around the bolts to keep water from getting in there and rotting, which is what happened to my original ones that came on the trailer. Which was untreated lumber by the way. I used treated lumber, and put 3 coats of stain on them and thought I did everything the way it should be done. Do you think if I put carriage bolts in and go through the carpet that the carpet will tear or want to pull away where I make the holes for the bolts to go through? I glued and stapled the carpet so it wouldn't be easy to take it up either. What would you guys do?
