Hi Bruno,

Assuming you mean to just leave it somewhere for awhile as you roam around, or go to stay somewhere, we have found usually to just ring around the various caravan parks and ask if they do storage, from any main Info Centre each state has a free caravan parks and accom guide, they don't list them all, but a helpful resource, my old home town of Strathalbyn (in another life) has a caravan park on the showgrounds, not sure how you contact them, but worth a try, a bit away from the rat race.

You could try typing in something like "Caravan storage in the Adelaide Hills" like throwing in a line and see what you catch.

Otherwise try the yellow pages, (on line) we did that for Melb in 2012, and found a storage place that specialises in vehicle storage. King Storage I think it was called, they did it all, so maybe have branches in all the cities.

Try the web sites for Top Tourist and Big 4 sites as well, some will store the van, but in the busy areas you may find they won't or are too expensive. You may have to go further out, even the Barossa is only a couple of hours away and there are some good spots up there.

Good hunting,

Bevan
