Groovy RackIt's an overland rack built specifically for the Toyota Tacoma. Made of aluminum construction. It mounts to the factory truck bed tracks (so presumably you dont need custom rails). Has laser cut framework and cutouts to help mount accessories. Attachment grooves along all four sides of the crossbars (for flexibility in accessory placement) Weight ratings: ~300 lb dynamic load (i. e. while driving) and 600 lb static load (i. e. when stationary)
