Hi Douglas,

We have just come back from a 5 week trip doing the Onddatta Track and Birdsville Track with our Harvok PowerBank Caravan. Speaking to numerous other caravan travelers, nearly all of them had some level of dust ingress. Even the Melbourn built full off-road van we were travelling with had more dust ingress than ours. We both used velcro stick on covers for all the vents.

I would probably speak to a caravan installer to see if they can fit a Carafan in place of the hatch above the bed, but I assume if they can install a Dometic DRS they should be able to do a Carafan – only difference is they will need to run wiring.

As per the Harvok reply above, we taped up the door seal and with the Velcro stick on covers and we were very impressed with our van, no dust ingress.  I did, as you will see on many You tube adventures, protect our pipe work and taps under our van with pool noodles.  As a comparison between the Harvok van and our friends van that we were travelling with, nothing broke on our van whilst their van had 2 broken windows, broken stabilizer leg and dust ingress they could not stop around the wheel arches.  Credit to Harvok.

Hope this Helps

Hi Doug,

We had one customer install the Dometic Dust Reduction System on their power bank, available at https://www.dometic.com/en-au/outdoor/rv-and-van/ventilation-solutions/rv-roof-vents/dometic-dust-reduction-system-339642.

We have not installed any carafan dust system yet. Can you share which dust extraction system you prefer? This may help other people choose the right option.

We have 5 cases in total regarding dust ingress, and they are all from the early Powerbank model (the 2020 model). Then we made improvements to the 2021 Powerbank model, and there have been no dust ingress feedbacks so far. The ingress was mainly from the door seal, vent, and hole where the cable goes into the van under the floor. We suggest owners check those places regularly to mitigate further dust ingress.

As you may be aware, we have gone to monocoque, which limits hundreds of joints that just put the water and dust ingress out of mind. Have a read here to know more about our monocoque construction: https://support.harvok.com.au/index.php/docs/harvok-knowledge-base/welcome-to-harvok-guide-to-new-owner-in-australia/understand-the-construction-of-the-caravan/

Let us know if the answer helps, and you can share this with any platform that people may be interested in to continue answering their questions from their personal experiences.

Thank you,

Is it still best practice to cover the 3x Ranger-branded rectangular screen panels? I can’t imagine how it would be safe to leave the batteries/electronics exposed.

Also, regarding the monocoque van variant, how are the electronics/batteries cooled and ventilated without vents (I’ve noticed marketing that says no need to worry about dust because there are no vents)?

Hi, Graham

You are right, covering those big vents on travel is the best practice.

Monocoque have rearranged the vent internally and one vent on the roof for fridge.
