Not sure of the rack brand, could be Con Ferr (that's what the clamps are), or some other brand. Heavy duty factory made rack, 42x48, with welded expanded metal steel floor. Includes six clamps. Probably too small for a 40, would be perfect to mount to a cage , was mounted to a 4runner? Asking 75.00 and freight from 79762 Odessa, Tx.
