I have a Lock-Right in my K5 and a Detroit in my Nissan. Both work great. The Lock-Right, had my carrier not had issues, would have been a breeze to install. The Detroit required a carrier replacement and that took some time to do properly.

I cannot imagine how fuel mileage would suffer noticeably with a locker installed. Under power the carrier will drive the inside tire in a curve and let the outside tire over-run the carrier. There is no loss of energy here. If I drive like "a normal human being", which isn't often, I cannot even tell there is a locker in either truck, except in tight turns in parking lots. I will say that the Lock-Right does make itself known a bit more often in normal driving though.
