Nothing major here . Just a simple nice feature that my f150 has. Going to pick up a dresser my wife bought on FB. I pull in this driveway thats gravel and pretty steep. Well i broke lose while i could have went on up the bank. I didn't like turning there rocks over. So i stopped pretty much on the steepest part. Engaged the Ele locker and crawled right on up without turning over any more gravel.

Ive found the ele locker very handy several times from snow to wet mowed hills to now driveways.

 

It helps a bunch. There are videos on YouTube showing the locker helping 2wd through sand, snow, hills, rocks etc. with the right tires, maybe a lift, a 2wd with locker is very dependable. 4x4 with a locker is unstoppable

 

My first truck was a 83 Toy 4x4 (still own). Almost new I go having fun pretty amazed at what it can do. I sit up on the top of Mtn watch 4 or 5 other guys struggle some not make it. Then comes super Jeep not even breaking a sweat. I walk over and start BSing with him. Told him the story pointed at some of the trucks kinda laugh some and than came the what the F is in that thing. I am locked front and read, you don't have to do the front but especially on trucks you lock the rear and you will be amazed. Saved me tons of times and has just become a requirement on my 4x4s (highly recommended)
