The Load Warrior IS a universal fit. You attach it to the VX's roof rack. I liked the way that everything fits on the LW but have not had any experience with the Thule.
Check out the Mods Section of Moncha.com. I detailed it pretty well there. Also, check out the Moab 'Zu Zoo IV Photo Album and the Moab 'Zu Zoo VI photo gallery, you'll find lots of photos show the LW off.
