I run a backpack strapped to rear rack with 6-hook cargo net. Extra stuff on my back is not something I want for 30 mi RT in 95-degree heat and 100% humidity. If backpack is full, handle is facing the saddle, bottom facing back of a bike. If it is semi-empty I fold it in half and mount sideways (bottom facing side). Two hooks go in front of the rack, two middle hooks cross under the rack and go on opposite middle trusses, last two hooks are fixed on rear trusses, sometimes criss-cross: right hook on left truss and vice versa. I also carry extra cargo net and couple cords in my backpack - just in case.

Clip rear blinkie on the net and ready to go.

Good juck
