What would be the maximum length cargo box one could put on the top of a Hatchback and not impact the antenna or the gate?
I doubt it causes any problems. I have had roof racks on several cars with moonroofs, and even with the roof open in the tilt-up position, there is plenty of clearance. Slide-open is not an issue if the roof retracts to inside the car. The problem can be wind noise, leading you to not want to open the roof when a rack is installed.Does your sunroof work with those racks?
