Short answer: yes, RAD Expand 5 will fit under the tonneau cover if you remove the right side pedal. I drive a 2020 F150 and our two expand 5's fit together side by side in the bed under the tonneau cover. I have 19 inches clearance under the cover. It's a tight fit side by side, but it works and the bikes won't slide around. Taking the pedal off gives you an extra 3&7/8's inches clearance under even fits in the trunk of my old BMW 328i!
