Discovery 4 Roof Loading

[mowog]

I am trying to find some facts about the roof load capacity of the Discovery 4.

On the web site it says 75kg this is where the confusion starts for me.

I have seen a few Discovery 4's with the ARB roof top tent. By its self it is well within the limit.

But how does the roof handle 2 people and round 200kg plus when people are sleeping in the tent?

Is the 75kg figure a dynamic load figure? IE pounding down dirt tracks with 75kg on the roof... That 75kg would impart a bit more load as the car moves.

So is there a static load figure for the Discovery 4 roof?

LRA and the RTA have put this as the max weight for the D4 for stability reasons, however LR UK state a higher max capacity, 150Kg from memory.

So it's a warrenty issue from LRA and a saftey issue from the RTA/ADR.

So that weight is based on whats allowed while travelling...

But the question is can the roof handle static loads over 200kg when camping...

It probably could, how many Land Cruisers do you see with RTTs and assorted crap on the roof, can't see why a D4 can't, seeing as from the factory the D4 has a higher roof load rating.

Discovery 4 maximum roof load is 71.8Kg(less the weight of the roof rails & cross bars) for "Factory Roof Rails & Cross Bars".
Discovery 4

For the Expedition Rack it lowers again to 54.3Kg(less the weight of the rack & rails)

So need to be careful when loading the roof.
While the vehicle is stationary it can increase, but i do not have a load reference for it tho'.

The ARB roof top tent I have will be under the max load... That is until someone is sleeping in it... Someone must have some numbers on the max static load.

Or are these people with roof top tents pushing their luck?

That is strange because on Land Rover Facebook page you can see three Discovery 4 starting an expedition from Geneva Auto Show to Beijing and they are loaded with one spare wheel (30 Kg) and four Fuel Jerry Cans which I think when you add all up it is more then 54 Kg.

In the uk they make a sweet looking rack....it is rated to 200kgs, and they advertise it openly.
