Test four positions
Check the carrier empty with the tailgate closed, opening, tilted, and fully open. Repeat with the intended load secured. Record shank rise, platform depth, hinge or latch path, exhaust outlet, lights, plate, camera, and ground clearance.
Do not stand in the door path or force the hatch against the carrier. A carrier that clears the bumper can still damage a door or create an exhaust and visibility problem.
Limits
No vehicle, carrier, load, or tailgate was tested. Exact clearance remains model-specific.
