I want to mount some manner of wind-deflecting cargo container atop the cab, but still have the flexibility to remove it to carry long items and such. I've been using a clamp-on Yakima setup, but it's a bit clunky to install and remove quickly and squashes the upper weatherstripping for added wind noise. My solution: turns out the Ranger Supercab roof has about the same curve as a 1986 Honda Civic wagon, so I installed a pair of those tracks which I happened to have. It's always a little nerve-wracking to drill holes in the roof, but they came out well, and the middle bolts lined up with the internal roof support beam. I sealed them well with butyl sealant left over from a recent window replacement. They're not too obtrusive as-is, so I'm satisfied. Next step is to figure out how I want to mount the cargo platform and/or a rack, and design it.
