G'day Chris,

Yes, absolutely.  The mounting channel is the same the whole way round, so you can easily mouth the ladder off the back.  The only consideration is the rear of your vehicle and if the ladder would fit. For example, if you check out the second to last product image of the Ridgeback mounted on the Prado, the ladder wouldn't actually make it over the rear of the vehicle/spare tyre.
As long as you've got room at the rear, there wouldn't be any issues.

G'day Doot,

Yep, it does include the rails, they 30mm deep.
Hope that helps.

G'day Joel,

The mounting rails run long on the Ridgeback, so the tent opens at the back of your vehicle.  The distance between the outer edge of the mounting rail and the outer edge of the Ridgeback shell is 27cm.

G'day Pustika,

You'll be fine to use a Megamat Duo in the Ridgeback roof top tent, but we can't guarantee that the bedding will fit and everything will close up properly - even with the valves open.  Best case scenario you won't have any trouble.  Worst case, you may need to pull your quilt/sleeping bag out.

G'day Michael,

The shell itself has a small row of railing with screw/rivet caps on the outside, and the width of this is 138cm.
The ladder mounts and gas struts screw to that railing and add an additional 5cm total to the overall width.
Hope that helps.

G'day Hammer,

We're not actually legally able to provide any advice for mounting these RTT, as we dont have your vehicle here to check out, and as this is being attached to a vehicle there are obviously potential safety issues if we dont get it right.
We've had a few customers recently who tried to get info from Darche for the install, but they're in the same boat as us.
You'll need to contact either your local roof rack specialist or qualified installer, or you can generally go direct to Rhino Rack who will point you in the right direction.

Sorry to not be of more help!

My apologies for missing that info, sorry!
The mounting bars are 77cm apart, and the bars themselves are 3cm wide.
The bars run from the hinged end, to the open end, and not side to side.
Hope that helps!

G'day Brad,

The Ridgeback that we have on display can be closed with the Darche 1400 Cold Mountain sleeping bag and some thin pillows left inside.
I'd say generally it shouldn't be an issue, as long as you don't have super chunky bedding!

Gday Matthew,

Yes, the overall packed height of 23cm included the mounting rails.

G'day Matthew,

As far as we're aware, you cant.
The awning itself needs to be secured to the roof racks or platfrom on your vehicle.
As you can see from the 4th and 5th product image, this is absolutely achievable with the roof top tent also installed.
Just make sure you are not exceeding the roof load limit of your GVM, which is different from the load rating on the physical roof racks.

We've got an update on this one.

Darche now have specific brackets that allow you to mount an awning to the side of their Ridgeback Rooftop Tents and they are rated to 30Kg per pair. We don't currently have them in our range but please enquire with our customer support team on 1300 914 007 if you would like us to get some for you.
