In our L322 we have the rear cargo rollup net (part number ERF 000030 https://topix.landrover.jlrext.com/topix/c...e-mobile=1), and we are really happy with this safety device. Not that often we've used it, but when we travel with all seats occupied and a lot of luggage, this net is useful.
If we end up with a new P400e - that only has 598 litres boot volume - I guess we might need such a cargo net between the shelf and the headliner more often...

But I haven't seen any L405 with such a solution We do not want to have a fixed metal cargo mesh as shown in the accessories catalog, it's still not that often we'll need it.

Do you know if such a rollup net can be retrofitted in a L405? If not, how do you L405 owners protect the passengers when filling up the boot all the way to the headliner with luggage?

Not seen one.

Was it even an option on later L322's ?

There is a clear perspex dog guard available somewhere - Emperor Mong had one at some point - http://www.fullfatrr.com/forum/topic26551.html

Well remembered Alistair.

I still have it. Very good it is too.

Might be an option, but it seems that this perspex glass is mainly a dog guard, and nothing you would pack your luggage against?
