I haven't chosen any yet. Personally I wouldn't go with a rack with 4 points of contact on the bed. I was leaning towards RCI since it has 6 points and a lot stronger. I had some disagreement with Kbvoodoo on their thought process on gussets and structure. Weight on your besides will cause it to bend and flex over time, they think bedside stiffeners to mitigate that issue are pointless. I disagree coming from the Tacoma community where beds flex and bend over time. I wont spend money on something that isn't structurally going to handle abuse.
I'm working with Mobtown Offroad and hopefully he makes a bedrack soon. He's into the Toyota business but hopefully he'll design one soon for the Raptor/F150 community.
