I have the E-LOCKER and have never had to use it because I don't offroad with it. It can only be used in 4LO anyhow so quickly switching it on while moving isn't an option. I love knowing I have it, and it's a plus when selling.2007 TITAN LE said:
Fuel mileage is stated as being the same ...maybe a mile or two difference. So if you're not going to be offroading, you could probably do without any of it. But....it's always nice to be able to! I wouldn't trade for a truck without it!
