Welcome back, pagemaster.
Why you ask this question? This is not a car for you, i remembering that you start to bash long time ago.. Be honest - you dont will ever drive this car
But, i will answer your question.
For my Transafrica with the Land Cruiser 200 - i thought also - i will drive as single car - and i have to do everything, to recovery myself alone.
So i add ARB lockers in Front and Rear, add a Winch, a well sorted Recovery Kit, Maxtrax Sandladders, an ground anchor and an airbag lift kit.
I had to handle many bad roads on our way (20`500 kilometers), had too to use the winch.
I used the additional lockers severall times - when i see that there is a bad track area.
But - more often the situation gets bad unexpected - several times i thought afterwards, that the locals did some traps - to earn money for recovery.
And guess what saved our ass each time?
A-TRAC and the electrical helpers - then i had no time for switching the lockers on. The "beeps" are annoying - but it saved us severall times.
So if someone would do the same trip with the same car - and wants to save some bucks and asks me - what to leave out of my recovery stuff. I will point to the lockers.
If my car gets lost - i would again equip it with lockers - but more - for driving hard stuff without warning "beeps" - and not have to read the manual - as when i think i be able to drive one meter further than without.
