I just bought my friend's 2007 Supercrew, and I'd like to know what most owners do for roof racks. I hope to get a canoe and/or kayak, so that's what is driving this question. I really hate the idea of spending $500 for a Thule brand rack. And I don't want to put a ladder rack above the bed. So, what works well for a "bare roof" crew cab F-150? Thanks. Chief
