Yeah I think that number is about right for what LR quote but I believe it's well undercooked.

You'd never be able to mount a rooftop...or should I say sleep in a rooftop tent if that were the case.

Obviously the force applied to the roof, being dynamic is increased but I don't think it would be to the extent of Rack + Tent + two adults (static weight) would it?

Besides, I'd never put that much up there anyway, usually lighter bulky stuff like a tent and chairs etc. Always ballasted with the heavy gear inside.

When I was looking for a rack in contacted this mob in the uk:

http://www.prospeed-offroad.co.uk/pr...cessories.html

I quoted land rovers figures, and they said that the roof was rated at that because the land rover products were rated to that weight.

They went on and stated that the roof will handle 200 kgs if using their rack.....offroad.

You would need to be careful with that weight though due to the higher centre of gravity.

Brett.....

The Landrover factory long tracks seem the most compelling apart from the price...wreckers maybe ?

Check ebay in US. They have the long tracks

Hello All,

I am looking into fitting Roof Rails on my D4.
I like the look of the LR Factory Full Length Roof Rails. The LR Cross Bars are not my preferred option as I like the Bar to go the full width of the roof to much things easier when lifting up kayka's etc.
Do not require a full flat rack, I only require a couple of Cross Bars to carry kayak's, ladders, timber, etc.

So I was thinking of fitting the LR Factory Full Length Roof Rails and add the Rhino Rack Aero RLT Cross Bars.
Does anyone have this option?
Are you happy with this setup?
Are you able to fit accessories to the Rhino Rack Aero RLT Cross Bars?

I ordered my D4 with the long tracks and bought Black (yes, black is available it generally needs to be ordered in) Rhino 1375mm long cross bars with the RLT leg set.
Happy with the setup. Up sides are:
- full width
- totally flat across the bars
- you can mount things like the multi holder or shovel holder upside down / underneath the overhang so you still have a low profile or full width available topside for other things
- you can fit spacers between the legs and bar if you need extra clearance so whatever is on the bars clears the tailgate when it's open

Down side:
- there is a little wind noise at certain speed but it isn't always there, strange? Only really noticeable with the roof open.

I'd recommend them.

Thank you for the feedback Rufusking.

I shall get the LR Factory Full Length Roof Rails and Rhino Rack Aero RLT Cross Bars under way.

The weights quote are always for dynamic loads not static loads due to crash tests. In my early days of training I was moved into a department that we designed roof bars, roof racks, trailers, truck trays, protection barriers etc. and it is always the dynamic loads we were worried about. So roof top tent and 2 people would be fine just not while moving. lol. Hope this helps with this thread.

Deleted, already asked.

It makes sense that the dynamic load would be the quoted figure, I think the suggestion is that LR have grossly underquoted. Of course, we'd all like to see that in writing. :)

LR's quoted 75KGs is the equivilant of a couple of jerries and a spare. Better than nothing I suppose but seems awfully light.

Wouldn't companies that make racks for D3/4 with a higher load rating than LR quote be opeing themselves to a legal bottom romping? It's hard to believe that they would be that stupid......but hey...LOL!!!

You mentioned crash testing, etc...can you shed some light on the test criteria? I imagine you'd have to be cognisant of rack and contents suddenly increasing relative weight due to a hard stop (read crash) and tearing the roof off the car. But have you more detail and figures? Doesn't matter if you don't, just trying to get a feel for the actual safe weights and the dynamic multiplication factor.

Cheers,

Kev.
