"I extended the height so that I drilled the holes about 1" below the top of the lower/ smaller channel."
YEAH, I did the same, but mine height clears the roof?? I also cut the top shorter so its easier to side the surfboards off the rack from the side. See picture
I know the height is to the MAX, I also added extra surfboard padding so the surfboard will be higher so the nose of the surfboard will not touch the roof of the truck (not in image). For the width I can't measure right now, my son has the truck for a trip
Awesome, please share some photos. I also did a lightweight bed divider, here's the link. I couldn't attach it on the rail since the rack is in the way. And needed it to fold since the rack is in the way

Updated my bed divider to make weight lighter. Really cheap and can find items in Offer Up or FB MarketPlace. I use material I already had, build 4 frames and sandwiched a free baby gate from Offer Up. Very lightweight.
Updated my bed divider with material I already had. To make weight lighter, I used 1x2's to build frame, and used free baby gate. Works great and very light
