Hello all. I purchased an old, reasonable condition flexiglass canopy for my 97 twin cab hilux a few months ago. Just recently I did a trip up to karijini and the surrounding area, lots of red dirt. I thought that the canopy sealed reasonably well but as with the red dust, it manages to get in. I do admit, the seal around the rear window could have sealed slightly better, but I didn't think that so much red dust woeuld have got in.
Any hints on proper sealing?. I think I will reseal the window, but anything else? . Does the tail gate let the dust in?, and if so how do I fix that.
I am also of the opinion now that it's time
To put a false floor in the back, storage underneath with the ability to sleep on top when required. What's the most appropriate wood to use? I'm assuming ply. Any tips and ideas would be much appreciated.

Hi mate

sorry to burst your bubble but it is mission imposible to seal a ute and canopy huge amout of dust gets in around the talgate but you can make it better, With my colorado ute i fitted a scupper vent into the roof of the canopy and when on dirt roads i open the forward facing vent and this pressurises the tub and keeps the dirt out, well most of it anyway !! Good luck

There are some canopies that seal well, the Australian work and Leasure and the triple M fibreglass canopies seal pretty damn well...these both go on flat trays.

But almost any canopy you can name that fits on a style side tray will leak like a sieve and that is from new.

There are just so many places they can leak.

Possibly the biggest is the bottom corners of the tailgate.

Gotta agree with the others. It isn't the canopy, it is the tailgate.
I am going to Clark rubber to get some seals for the tailgate of the Dmax.
I like the idea of the vent. Tell us more pmacks. Where did you get it?

Sealing the back of the ute to 97% is rather easy, I have sicaflexed a sheet of 12mm ply to the floor of the tub and put carpet on it, I got a piece of 30 mm ally angle and pop riveted it to the floor and up the side, then used a piece of left over door seal and placed it on the angle to seal against the tail gate ( measurements were required).

The only place the dust gets in is in the corner between the canopy and the top of the tail gate, nothing that can't be stopped with a piece of rag.

I will post photo's tomorrow if I can get some time.

Phil.

Hi Guys

Here are a few photo's please note I havn't cleaned the back of the ute for a few months so there is a bit of dust there, however you can see that what I have done does work to about 90 odd %with a bit more time and perhaps a different set of eyes it could be improved.

The last one is where the dut gets in, hope this helps.

It's not only the canopy that you need to seal. Checkout your tailgate gaps.

Peter is spot on when he suggests a vent. This creates positive air pressure inside the canopy and will exclude any dust from being sucked in.

I have an ARB canopy and vent and can positively state that it works.

Yes, I concur, the ARB canopy with vent is great.
This is placed up the rear of the canopy and the pressure pushes air through any gaps keeping dust out.
Can be open or closed.

In convoy, you just need to stay well back if following others, but of course that's wise for air intake as well.
The vent location at the back helps with that too, any minor dust ingress from the intaken air is straight through the tailgate gaps.

I've often thought a home made vent could be made with a 75mm or 90mm PVC pipe elbow, have it so it can be turned forward or back (in heavy rain I shut the ARB vent, as it does allow some water ingress when it's heavily raining).

You can buy the ARB vent, think they were an optional $55 or so when I got mine, not sure if more bought seperatley.
Didn't see it, but suspect it is an oval or rectangular cut in the canopy to fit.

Just looking at the tail gate and the canopy now, yeah, the gaps at the bottom corners of the tail gate are huge. I will work on sealing as much of the tail gate first then look into the vent idea, hand in hand they should work well

If trying a roof vent, don't seal up tailgate.
The airflow is needed to allow the air movement from pressurisation.

Clark Rubber have self adhesive EPDM rubber strips in various widths and thicknesses that will work a treat at sealing the tailgate. You also need to check the front of the tub where the floor joins as there is normally a gap there to stop the tub filling up with water.

Oh, another question I had to ask. My canopy has one central handle/lock on the rear door which pushes 2 long rods to the outer sides of the canopy to lock it in place. I don't really like this setup as it is often a pain to close. Is it possible to remove this and put 2 separate handles on either side of the canopy door?. Are accessories of this kind available?

Gooday Grant, I used to have that trouble with the canopy on my BT 50 but one day I opened the side sliding window just one notch and have had minimal dust problems since.
At one stage I was following a loaded B double log truck for several kms along a very dusty gravel road and still no problems.

Just gotta remember to shut the window when its raining.

All the best, Gary M.
