Do you have Rear Diff Lock?
Do you all order the Active Rear Locking Differential or the Capability Plus Pack? I did not and know have some concerns after watching some LRD5 off-road videos. Was that a big mistake?
What do you think? Is it a must-have option or it is fine without it? I doubt I will do super offroad hill climbing or stone crawling, but in some cases will go off the road into the mud and forest of course.

Not needed - it will be fine without. The locking rear diff just makes 'extreme' off-roading easier. A Disco without will get to all the same places, it'll just need a little more oomph!

Locking rear diff will be most useful only if towing in low-traction areas like wet grass, mud, etc. Center diff lock with all the technology available in these things is plenty good. I have an HSE with the Capability Pack (center locker only), and I have been offroad in mine over wet granite and shale on inclines >>10% and it's fine.

I have had the rear locker on my Disco 4 and it did make a difference in the sand. I didn't really objectively test it against any vehicle without the locker, but compared to my Disco 3 which didn't have it, it felt like it had more traction when beach driving on soft sand. My current Disco 4.5 doesn't have it and I haven't missed it. If I was speccing up a D5 from scratch I think I would include it, but if buying off the showroom floor then I'd probably just take the one with the best colour.

I ordered mine with the Capability Plus and tow package. The LR3's with the locking rear differential are in high demand on the used market so I figured it would make it more desirable in the long run. I also tow trailers and a locking rear does come in handy on occasion.

I've got the e-diff on my D4 and have ordered it on the D5 as well. As said above, I think it only makes a difference in the extreme stuff. As I have a poverty pack D4 I've never been able to tell when it is engaged but it does walk up steep rocky inclines with very little wheel spin at the back so I think it does its job.

As someone who has not had a rear locker on 4 x D3\4's I can confirm that I never had a problem getting anywhere those with one did, even in the most extreme off road scenarios. As Stu points out, it might have taken a few seconds longer to get there but the independent power to wheel traction control takes away much of the need tbh
Personally, I think offering one was more of a hat tip by LR to those historic enthusiasts who would think if it didn't have it then it wasn't a proper LR or off-roader, rather than adding a significant benefit.

As above.
First D3 - didn’t have it. Don’t think it made a difference.
D4 (recently departed) - Had it. Made a difference...but marginal at most and just made it seem a tiny bit easier one or two times on steep, rocky climbs.
D3 “for off-roading ” - doesn’t have it and don’t miss it compared to the D4
D5 - couldn’t be bothered to spec it....
Maybe that helps the decision

I think the only advantage a diff locked D5 (or 3/4) has is less strain on driveline components is extreme situations.
Without the locking diff when a wheel loses traction, the brake is applied to that wheel, transferring the drive instantly across the diff to the other wheel. This does put a strain on all the components across the axle.
With a locker, as soon as slip is detected, the diff itself locks and sends power to both wheels on the axle, so less strain on all components.
Not that I know of any rear diff or driveshaft failures in D3’s or 4’s without lockers in off road severe situations. Seen a few front driveshafts fail, but that’s not going to be helped by a locking rear diff.

The comment on strain to drive train components is interesting
Take a look at the recent Grand Tour epsiode where they “tested” a Velar, Porsche and an Alfa. Both the Porsche and alpha under moderate use went into limp mode due to 4x4 overload. Crap softeoaders. No such issue with the Velar
Also didn’t realise the velar does not have low range.

No low range though it can be had with the active locking rear diff.

Sorry, do you mean you can get a Velar with transfer box if you spec the Locking Rear Differential?

Meant to say 2 speed transfer box!

Gareth, Velar only comes with a single speed, torque on demand transfer box on all engines. On V6's only an electronic locking rear diff is available as an option.
