Indeed. The D2 was an interesting compromise, being monocoque over ladder, as were most LR cars from D2, P38A, right through to the last gen RRS. In fact, I believe the D1 gets a guernsey as well, but it wasn't nearly as safe. Just like RRCs.

Don't get me wrong, safety is good, especially for those who have kids. LR's work needs to be respected. The structural integrity of Mark's D4 saved his life. I used to tool around, on tracks like that, in a G60 Patrol ragtop. Everywhere at full throttle because that is the only way the car would get up. A crash like Mark had was easily on the cards, but the difference is, I wouldn't have survived it, unless I was thrown.

did the crash barrier, in your opinion, aid the structural integrity?
my understanding from the comments on the video is that you were a little off your chosen track (line) and hit the step in the gully and this is what caused the stall.
i've been known to be wrong before though.

Regards.

Not referring to the D3/4 specifically here - but Im not convinced that cargo barriers will offer anything significant as far as structural integrity goes. 4 years ago I went through a fairly significant rollover (highway speed) in my old 80 series landcruiser. The most affected part that got crushed was the A and B pillars. The C pillar where a cargo barrier would be (didnt have a cargo barrier in my cruiser as the 3rd row seating was being used) was hardly affected. I just belive that the extra strength needed for a rollever is up at the A and B pillar as the engine seems to weigh the front down a bit.

Cargo barriers are definitely worthwhile in terms of stopping cargo coming forward - I had one in my CR-V. Also lets you pack soft-stuff up to the roof. I'd fit one permanently in any vehicle where I wasn't using third row seats. But they're not fitted hard against the roof so if they were assisting in a roll-over you'd expect to see the roof crushed in to the top of the barrier. In any non-monocoque 4WD that would probably really help. But there's video on YouTube of a Range Rover barrel rolling multiple times at speed and when it comes to rest the body looks remarkably intact, including the C pillars and the area between the C pillars and I'd guess that the D4 would be similar, so an
internal roll cage probably isn't needed.

Just watched Stefan's video. Very glad that you are OK. The car is just glass, metal and plastic, but you are are precious and vulnerable.
There is no doubt that the D3/D4 are incredibly strong.
By the way, welcome to the club (Pub with no beer - Anzac day annual pilgrimage) that noone really wants to be a member of.
Again glad that you are OK.
Cheers

Thanks Mike
I did recall your adventure whilst I was thanking the stars the night I rolled. At least there was a pub (with beer/whisky iirc) nearby for you to self medicate.... I was in a field...
I hope the club membership stays at us two....!

Thanks again

There was a pic in the Milford adds for years of a D1 that had rolled,the barrier did a pretty good job of stopping more damage to the rear section of the vehicle.
I think the vehicle may have been owned by someone on here.

I have had one fitted to every wagon we have ever had,in my opinion they are an essential piece of kit,both for safety and help with packing gear in the rear section.
They are easy enough to remove if the rear seats in a seven seater are used.

In fact,in a dual cab or single cab ute, they should also be fitted just behind the the rear window,no matter whether the vehicle is a tray back,tub back or is fitted with a canopy.

not having a go at you personally LRD414, but really?

Part of really growing up is being able to put a sentance together without swearing

I’m really torn on vehicle....
Used 2.7 D4
Used 3.0 D4
New D5....
Wait to see what the Defender is like.

My timing is shocking...would’ve held onto my D4 until new defender comes....and then make a decision.

A nice / not so nice position to be in !!!!

With the new defender so close, I would wait, or get an intermediate. The best defender might also not be straight away, the SVX may come later as was the case with the SVX disco (uprated susp, winch etc)

And being able to spell?
*sentence.

You set that up, I just had to hit it out of the park.
