Hi all, have just placed an order on a 16-49-4 OB in preparation for a 3 month Vic-SA-NT-WA-SA-Vic trip from July - Oct next year. Coming from a soft floor camper trailer and after threatening to upgrade to an Expanda have finally done so, particularly thanks to the raft of great information on this site, thanks!
I'm building a list of modifications and one item on the list is dust sealing. Ideally we want to be able to tackle the gibb river road etc conditions permitting.
Apologies if I'm repeating other threads - I'm reading various solutions, including:
1. Sealing all gaps underneath the van, particularly hose and cable entry points and the potential big gap at the rear where the fibreglass meets the floor;
2. Ensuring a tight seal on the front and rear doors;
3. Covering the various vents; and
4. Positively pressurising the van via roof vent or other.
Given the the van will be fairly new, I'm keen to avoid the hole in the roof option if at all possible so I'm keen to hear how much success others have had at keeping dust out using the other solutions other than positive pressure?
From reading the various threads, I've interpreted that solutions 1 - 3 above seem to do a pretty good job at keeping the dust out without having to positively pressurise?
Cheers,
Shane
Hi
@Shane74. Congrat on the upgrade.
We've been burning round the place since Dec last year and done 1000's of km on dirt, gravel, sand, dust, mud and of course the relentless corrugations. Before we left we did quite a bit of work to the van, and I rolled around under it on a creeper goo gun in hand and filled everything I could find. I sealed along the junctions of the wheel arches as well. Whatever sealer they used on my van Urethane wouldnt stick to it, but Sika Roof and Gutter did. After 10 months on the road we recently sprung dust leaks in the lower cabinets around the wheel arches and I suspect the vibration, heat, dust and flex got the better of it. I washed it stripped out the sealer and re did it and that seems to have worked,
I don't block vents at all, I have a piece of trampoline mat I shove in behind the lower fridge van vent "sometimes", if I rememeber which isnt often ... then I forget to take it out. Actually I think its in there now. You will get dust in if you travel on dirt roads long enough, its unavoidable but we havent found it bad. Positive pressure wont work so well in our van because we have 3 large Dometic roof hatches and they dont seal because they provide the gas venting
We didn't find the dust in the Gibb particularly bad, we've certainly had far worse.
