Dual Cab Ute Dust Problems

Graeme
I had a D40 Navara with the same issue. I had to leave my canopy front window open as well. I also pop rivited two strips of aluminum flat bar up the insides of the tub near where the tailgate meets. I then put two strips of adhesive back foam on the ally strips. This sealed the sides of the tailgate, and then used a piece of foam to fill in the bottom gap of the tailgate and cut the foam to go around the hinges.
I hope this helps
Regards.

I know Mitsubishi have a dust seal kit for the Triton. Have you approached Nissan?

You can buy the generic dust seal rubber from Clark, maybe you could make up your own seals?

I have a Hilux and I had a vent inserted into the roof of the canopy.
I got it from a 4 x 4 shop, cost about $85 fitted (if I remember correctly).
The vent faces forward and forces air into the back at force, which stops dust coming in through the tailgate etc.
Yes, you will get some dust from oncoming traffic, but it is minimal.

Hi Graeme

I have a Colorado dual cab with a ARB canopy, with side & rear lift up windows.
I fitted a vent to the top of the canopy at the rear facing forward. on dusty roads I open the vent ,this causes a vacuum that stops most of the dust entering . add to this I have fitted foam rubber pipe tubing, cut so it laps each side if the tailgate lip on the bottom and sides resulting in minimal dust penetration.
Even worked with bull dust and passing road trains.

I have a D40 with a hard cover and had the same problem. Simply purchased some foam with self adhesive and filled the gaps between tailgate and body and not a prob since (4 years ago) If you close tailgate and look down you can see that especially at the bottom there is probably a half inch gap (yeah I'm old not mm) Did around the sides also which made the tailgate also a nice tight close. As said no prob since doing so and one does only have to look at the huge gaps to see why the dust is a prob.

I installed 2 of these.https://www.whitworths.com.au/main_itemdetail.asp?cat=156&item=92551&intAbsolutePage=1, Cheap and very effective.

I have a Dmax with Alpha canopy and was told the same thing about opening the window.It still gets dust in the tray and like a lot of others, there are huge gaps around the tailgate.
I went to Clark Rubber a couple of days ago and the guy knew exactly what I was after. He came out to the ute and measured the tailgate, went inside and cut me a length of sticky backed foam strip. It's 12mm thick and slightly softer, he had a harder one there but said the softer one is the way to go, because it will form around things better when the tailgate is closed.

I'm not sure if all utes are the same, but when I was talking to the guy that fitted my canopy, he pointed out two small holes that are on the back of the tray below the back window. He said he used to get complaints from people saying that the canopy leaked, but it was water coming in through these two small holes.

Once I have done the tailgate, I will see how it goes with just opening the rear window. If I still have dust problems then a vent will be the next thing.
