Dust proofing a Dual Cab

forward facing vents as high as possible, i have seen them with "rain" traps on the work utes we used in Darwin, not an ounce of dust came in as it pressurised the canopy, the rain trap stopped the water in the rain, and heavy rain at that .... just like the snorkle tops that seperate the water ...
Cheers

I have an ARB canopy on my dual cab and fitted a vent (also from ARB) to the leading edge on the roof of the canopy. It's only small but boy does it work.
The vent can be fitted either front or back, as long as it's facing towards the front.
I fitted mine to the front as I also employ a roof rack and cage when travelling and the vent sits just below the front cross rack.

The only dust that I notice now is a small amount along the bottom edge of the tailgate and I can easily live with that.
Perhaps with cargo drawers fitted, the positive pressure is reduced along the bottom edge of the tailgate, but it is nothing of concern in my case.

From memory the vent was around $40.00 and is easily fitted either by yourself, or "in shop".

The vent can be closed and this is the way I leave it around town, but flipped up when off road and it works really well to keep the tray area clean.

I have had 4 dual cab utes and always fit canopy with sliding window on front ( behind rear window of ute ) and when on dirt road leave the window slightly open ( 25 mm ) . This works the same as above solutions pressurising the canopy and keeps out nearly all dust .

Had the vent as well in mine but must remember to close it if in heavy dust and following some one else other wise work well. In regards to tail gate I had 2 1.5m alloy plate made up approx 10cm wide and height from floor to top edges of utewell. Bit hard to describe and dont have any pictures handy at the moment but it ran vertical from floor up level with top of tailgate. I pop riveted one half to just inside where gate closes and put rubber seal on the other half that is hanging out so when tailgate is shut it closes up against the rubber seal. Along the bottom of it I used a strip from bunnings that you put on the bottom of a door but it was like very light brush, I reckon it stopped 99% of dust coming up through the gap on bottom of tailgate. never had any issues with the canopy itself with dust or water entering the rear tray, was sealed down with rubber strip then I had 6 clamps, two on either sides and two up front pulling it down nice and firm but could take it off in 10 minutes if I wanted to use it as an open ute Definately one thing I miss with having a prado.........and dogs in the back of the ute is the best place for them when there wet and sandy........................just hose them and the ute out

Those solutions work well provided you don't travel in convoy for protracted periods on dirt roads and/or you don't fall into huuuuuuuuuuuuuuuge bulldust holes like I did. I've managed to seal the rear of my D40 using low density foam with sticky on one side. It has now been in place for 3 years and still holding up.
