I have the Chief Full Roof Rack System fitted to our 2019 Laredo. Mounted to that is a Darche Eclipse 180 V2 Awning (highly recommend) and four Maxtrax on mounts and in a Drifta Maxtrax bag. The bag I got in the process of trying to eliminate a bloody loud whistle that developed once I fitted a flush style of Maxtrax mount. The whistle wasn't there when I had a mount that raised the Maxtrax about 50mm above the rack. The whistling wasn't reduced by the use of the bag (kept it on, looks great and helps keep prying eyes/sticky fingers off the Maxtrax) but disappeared once I fitted a length of black composite decking plank in the gap between the two roof rack planks above the included Chief hidden air dam. This completely blocked the gap between the first and second plank
