James hussman I had a hard time getting my hands underneath the aluminum panel and because I used lag bolts I had to turn the wrench underneath to tighten it which was very difficult. I was only able to do 3 because I couldn’t get to the very back corner to turn the wrench. It is very solid with only 3 bolts. If I had to do it again I would use bolts where I could just hold the wrench underneath and tighten from the top. I’m very happy with it and wish I had it a long time ago. I’ve used it as well as the kids and getting back in the boat is so easy now.
