Thule Motion 3 XL Low Pro - An update on the best selling roof top box ever

[@kylevuong]

Can you tilt or open the sunroof with the cargo box installed?

Any noticeable change in MPG if so how much?

[@Engearment]

Great question. We did not notice a drop in milage. If I had to guess, perhaps .5 MPG.
