I like many on the boards own an unlocked 80 Series and while I would much rather have had the vehicle originally equipped with them, I question just how much more capable a locked vehicle would be. Let me rephrase that: How capable is a non-locked 80 compared to a locked 80? All things equal (driver skill, tires, suspension) can you get through, let's say, 75%, 85%, 90% etc, of the same terrain okay sans lockers?
