I'm building a slider and its going to be an "A" frame shape. The top center piece is right at 20 feet. Its going to be floating so I was wondering from you guys that have experience, how many barrels will I need to support it. I was thinking about every 6 feet or so having one on each side of the center piece. This would put me at 6 barrels. Are 6 barrels enough to support this thing because it's starting to get pretty heavy the farther I get into it? Thanks.
