the ride... the nicer it rides.. the less weight it can handle..
"Ford" offers 3 different front spring rates.. and 4 rear spring rates...
so NOT apples to apples..
the Ford E-locker is Super.. and will automatically unlock at 20 mph.... and its a True Locker... under electronic control.
an electronic solenoid locks and un-lock sliding pins in differential.
and yes.. 3.73 and 4.30 uses same E-Locker.. so just a gear change.
my 2012 has the E-Locker.
My Ford rides like a Truck.. not a car..
but my truck has Tow and Slide-in camper options... so it rides Hard empty.
I lower the air pressure in the tires...when empty.
