Hello all. I have a rack that mounts similar to a lumber rack but uses a round Yakima crossbar. Looking to carry lumber and other heavier materials and toys where Yakima crossbars would fail. I was going to purchase 6061 aluminum tube that’s 1.125” diameter with .25” wall. Wondering if I should get a solid bar instead for strength or if the hollow tube is sufficient. Any other suggestions would be greatly appreciated. Thank you.
