Yakima does have a ton of options. I've had yakima racks on all my vehicles: Grand Cherokee, Disco II, and F-150 CrewCab. In the past I have had ski racks (still do), bike rack, and load warrior. Like you said locks are a must! The rack system on the Mini is just like Thules and Yakima's base rack system. They both have the quick release system. The only differents is the track which gives you the option of sliding the crossbars.
Unlike my old F150 the way our trucks are designed the Q-towers with the clips that attach to the iniside of the door will not work. Drilling holes is the only way of attaching some sort of roof rack system. I have been want to do this for a while now, but never had the nerve to drill holes into my truck nor womeone else doing it. After watching an installation video at
Rack Attack - Thule Rack, Yakima Rack : bike, ski, kayak, snowboard, cargo, I said, "F#@$ IT!!!"
I just ordered the Yakima's: 54" track, control towers, land pads #1, and 50" fairing. I already have the crossbars and locks from my old rack system. I went with Yakima b/c the plusnut looked more secure. Please someone correct me if I'm wrong. And, Yakima just looks better!!
Sorry for the long post, but I will take pics during progress.
