I have been debating on selling my Sherpa Crestone rack for the ARB alloy flat rack, but noticed Ironman 4x4 offers one very similar:
Alloy Flat Top Roof Rack - 6''' Length Suited for Toyota 4Runner 2010+ - Ironman 4x4 America
Dimensions are different, with ARB's at 70"x44" and Ironman's at 72"x49.2". Mounting hardware is different (and currently out of stock) but may fire on the platform to take advantage of their Black Friday code.
Anyone running the Ironman rack, and can you share photos if so?
