About to hit the outback and want to mitigate dust in the van, so what are your thoughts on how to seal vents? My Jayco has 4 vents including one for the fridge, which we plan to run at the time.
Cheers

If you re sealing vent, remember to open them up again each night as some of them are there as a safety vent in case of gas leaks.
An air scoop towards the front of the van will help pressurise the van and stop the dust from being sucked in.
One handy hint, if the external sealing takes on the colour of the dust, just spray it with silicon spray and it will wipe clean.

We have a 16 ft Jayco poptop caravan. It has a 2 piece door with a security screen on the inside (plus flywire) and the main door outside. There is a vent in the bottom of the outer door, which we bung up with a piece of squishable foam carpet underlay. We open the outer door, insert the underlay and close it all up again. When we get to the destination, we remove the foam. It is usually full of dust so we bash it to clean it and it is ready to go again. We also have a scupper vent in the roof to pressurise the van whilst travelling. The foam must be soft enough to allow it to squeeze up and seal, but it must not be to thick or it will distort the door frames. We found carpet underlay to be ideal. We have had the van from Nocundra to Tiboorburra, and at times we could not even see the van because of the dust. There was virtually zero dust inside the van, and that was before we fitted the scupper vent.
LPGas is heavier than air, and therefore you must remove the door seal once stationary or any gas leakage will not be able to escape out the door vent

I’m a true believer of the positive pressure system, have had one on all sorts of vans, campers etc. for over 40 years but they have to be filtered it you have just a fwd facing vent/fan etc & not filtered & you get caught be hide or oncoming traffic a dust storm etc all your doing is swapping the way dust gets in, computer vans work
well on campers & canopy’s etc. bigger vans etc. need more & present on my large slide on I have a Davis craig fan going thru a Holden air filter, have a great trip

Depending on your vehicle and trailer combination you need to be careful with scupper vents, particularly if you have a camper trailer where the roof-scupper vent is low, usually below the roof height of the tow vehicle. With our original combination of Ford Maverick and Goldstream Crown the scupper vent was effective. The previous owner towed with a GU Patrol and said the scupper vent worked with that combination. Not so with my current Pajero, the rear spoiler directs air downwards and even at 70 km/h throws up a huge dust cloud, which, without a significant crosswind envelops the trailer, with the scupper directing it into the camper. If I was a more confident with metalwork/hacking holes in the camper body I would fit an air filter-bilge blower positive pressure system such as that described by Vince M.
