Reviving an older thread, I'm considering the jump from my MY12 TDV8 L322 to a MY21.5 D350 L405. Whilst price-wise they're probably ball-park with what I paid for the L322 nearly 10 years ago, it would be a shame to run it in such a dirty farming environment. I think that a Defender would probably be more suitable for me but not for my wife. The D350 seems to always have an e-diff and the engine performance isn't the backward step of a D300, although I'm sure that it would be more than adequate.
