How do I mount an Alu-Cab rooftop tent onto a Sherpa Crestone roof rack, and how should I attach the load bars to it?

Standard rooftop tent mounting brackets between the Alu-Cab low-profile feet and the Sherpa crossbars generally work best — Sherpa's own tent mounts often don't leave enough clearance against Alu-Cab's wider mounting tracks. Because Sherpa racks are usually recessed, you may need additional feet to raise the tent to the correct height. Alu-Cab crossbars themselves attach to the Sherpa rack using Alu-Cab's low-profile feet.
