Anything that uses those cheeseball stamped steel gutter mounts/risers are nothing but POS. After you get some real gutter mounts the rack itself is only as good as the design, materials, and workmanship. The POS rack I built as shown here https://forum.ih8mud.com/showthread.php?t=33304 with tree branch lodged and seperated from tree in pic #1...has also carried 12 6X6X16' pressure treated up there as well. Ya, I know a bit over loaded especially with only 4 quik-n-easy gutter mounts spreading the load. I'd pay good money to see those POS poser Yakimas et al do that. Buy and/or build want you want...just understand what you getting in return. .....man I'm in a pissy mood tonight.
