L200 has a solid rear live axle, and independent torsion beams at the front which allow excellent articulation bit with more accurate axle location, and better steering manners on the road.
Separate chassis, just like a Landy. High level breathers which vent inside the chassis rails make it a much more durable wader than a Defender, and they have an extra 25cm wade depth over a stock Defender.
Add in the locking diffs that the Defender doesn't have, and a structure that isn't rusted to buggery in 5 years and it kicks the Offender in the nuts, flushes its head down the loo and steals its lunch money.
I've done the Land Rover thing for many years, and love them as I do I'll never go back now I've tried Japanese.
