Intelligent Ideas ?

 

On here, come on Pipes!

Pressurising is the only way to prevent dust from getting in, and that won't work 100% anyway. For starters, you probably have vents in the bottom of your access door (to let the heavier-than-air LPG out should you get a gas leak). For travel purposes, you could block this off with some foam carpet underlay, BUT YOU MUST REMOVE IT WHEN YOU ARE NOT TRAVELLING - just in case you do have a Gas leak).

 

I would re-install the big scoop at the front of the bus. This gives you some hope of getting enough air to pressurise. Opening any window, particularly the rear windows is a disaster because the rear of the vehicle is a dusty area on dirt roads and that will bring in dust for sure.

 

You should check other areas where dust can get in - the back of the fridge, under cupboards or beds, wheel arches and past the window and door seals. Try taping the seams up as a temporary measure and if you get improvement, this gives you an idea as to where the dust comes in.

 

It is not easy, but it can be done, and SWMBO will thank you for it as well.....

Pressurising your vehicle only works if you are the only vehicle on the road.
At some point you will have to follow another vehicle on a dusty road and any front facing system just allows even more dust in.

 I have a 100 mm Dia. Bilge Blower Fan fitted into my Avan Cruiseliner.  Drawing through a filter.   It pressurises the Avan which is not all that big folded down. I still block off all the vent openings in the van if on Dirt roads for 4 hours or more travel.  We turn the fridge off and put blanks on the vents. Been using it for about five years now when doing extensive off the blackstuff traveling.    Works well.  

Switch in the Dmax for putting the fan on and off say for  a minute when a big truck passes by with following Dust Storm. But if I forget the filters stop the dust anyway.  Shaking the filter material out when necessary.

 

Good luck with it Pipes, I reckon its witchcraft lol. Just took a standard on road van along the Ernest Giles Rd, Mereenie Loop & Plenty Hwy without any sealing up of vents whatsoever - hardly any dust in the van, but the back of the tow vehicle was full of it & we had done all the right things in the car (windows closed, vents open, A/C on) - I was expecting a lot more in the van & none in the car. Go figure! :(

Also thanks from me for all the above info

I have just done approximately 10 kilometres each way on a good gravel road.

I travelled at 75 KPH so that I could actually see if anyone was behind me, and there was no one in front of me

There was some dust inside my Fiat Ducato Jayco, Conquest vehicle, on the first run going into the area, but much more dust on the second run coming out of the area

I am thinking, does the wind direction make any difference, because on my vehicle, the exhaust outlet is pointing down to the ground

The exhaust is on the drivers side, and the vent at the door is on the passenger side

Perhaps on the way in, the wind had been blowing the dust away from the door vent, and going out the wind had been blowing the dust towards the door vent

I have previously noticed that when I travel in the rain, there is water on the door step near the vent
