Capless fuel filler and dust
 
We are presently in Broome, having come across from the east via the Plenty Hwy, and the Kimberley. Several thousand k of very dusty dirt roads, and as the fuel access actually collects dust, a number of times on our 2012 I've had to dig out the cap from dust and carefully clean the neck before refueling.
This situation of dust collecting would be the same on the 2014, but with the major difference that there isn't a cap to help shield the filler neck from the crud that surely is going to get down into the seal area.
Are there any solutions around?
A change of model is on the cards for us, but I don't want to go from frying pan to fire.

Not sure how the seal on yours is, but for MY14 it is just around the door.
The filler nozzle sits back from the door. If more sealing is required, it would be easy to either fit a secondary row of sealing, or I am sure you could get some form of cap/plug to seal the opening shut.

Among a few other design oversights, the capless fuel filler is the most ill thought out, dumb and downright bloody stupid feature of the MY14.

For those spending any more than a km on unsealed outback Australian roads, the outer door will not seal the dust out. Even placiing a small rag in there over the top of the cap would be better than nothing. I'd be very wary of putting anything (i.e. plug) inside the filler neck, as it may break the seal, worsening the situation. A stubby cork shape might work but I doubt the throat will hold an internal plug secure enough on rough roads. If considering those plastic multi-fit type fuel tank caps; the outer shape of the filler neck doesn't bode well for a proper fit - they are likely to be too loose to be of any real use. A good way may be to use a small heavy duty plastic bag of some sort and zip clip or rubber band it around under the neck collar - but that would be fiddly and a PITA each time you had to refill. Before any of the above, try a (large size) condom (or two) - tight seal, quick, easy, disposable :)

Lastly, have a look at installing a Racor, just in case!

Photos were much appreciated.
The 2012's don't have a seal around the door so that may be of some benefit.
Diesel film does attract dust, and it seems to me that it could be an issue......places we take our vehicle anyway.
I'm hoping for an answer like - nope it isn't an issue, and here's why.......
Someone must have had their new truck filthy by now.

I was thinking of a rubber style plug with a rather slim cap type section so it wouldn't protrude so far as to put pressure on the door. If it is rubber or silicone then it should be able to deal with vibrations.

Something like this could work.

I think I have seen that object in a few videos before . . . .

I did get a suggestion from another owner who folds a small hand towel over the cap before the door is closed. He says that works a treat for him.
Thank you again Snuke for your suggestion however these days my risk tolerance is reduced so best I not go any further with that.

Very interesting plug design P/N A55-CRAK, but I think if I get dust and dirt inside the door I'll do a Form In Place seal(FIP).

You are one bent unit Snuke,
Very enterprising of you, sure it won't leave you short else where? ;)

On a more serious note. The capless cap section actually comes away from the filler. Push and twist anti clockwise and it will pop right off. I had a dust issue and was able to remove it so I could clean it. Seems to work ok. I actually stick some foam in there and shut the filler door on it. It was an old car washing sponge cut to fit. Not sure if the seal on the door that let the dust in in the first place or it was my wife not closing the flap.... either way haven't had a problem since.

Snuke, is that one of your plugs?
