I thought it was all a bit over simplified also.
The Landrover has a centre difflock with a locking rear diff( I think) as standard
The Landcruiser has electric locking diffs front and rear as an option (about $4K in oz) but these were not fitted to the test vehicle and it was made to appear as if the landcruiser was lacking in off road abilty.
The Landcruisr has a rear LSD as standard in Oz ,Im not sure about SA
The LR does come with good offroad AT tyres in oz and because of this its often referred to as "the best out of the box 4wd in the universe"

The 7* with split rims usually come with a cheap Dunlop Road Grippers but I think the 76 and 78/79 RV's get some better rubber,might be Goodyear Wranglers
Last time I looked at prices a similarily equipped 78 troopy was $10000 more than a LR 4dr wagon.
I would like to see the V8 diesel 7* series up against the new LR with the Ford Transit turbo 4cyl diesel,2.3 litre?
