Do you have a link to those gutter mounts? I a have the Surco, but I don't like the optics.

Just search for Van Gutter Mount Ladder Rack and lots of options will come up. My setup didn’t need the crossbars so I just threw them away, just be sure to check if they are removable if you don’t need them (most of them are). I don’t know if I got lucky or it was pre-“supply chain” issues or whatever, but I can’t seem to find them cheaper than $65 now.

Custom voyager rack. I don't have sunroofs so had them keep the height the same from the front to the back and it is as low as the factory rails (can't go any lower then that) with an iKamper 3.0 mounted on top.
