If your not doing any real off road travel most campers should be ok... Even an ordinary van (with suitable preperation ) should be ok for around OZ via the coast, many are doing this..

Storage space maybe your biggest problem..

Enjoy your trip....

I did the block, including Gibb River Road, Gulf Track, Fraser Island and various tracks along the way with a Golf off road camper, wife and two kids. Five months of absolute heaven on a stick. No problem with storage - how many pairs of stubbies and thongs do you own? A little planning goes a long way. Pack all the clothes you think you need then throw 2/3 of them back in the house. Lots of room with this set up, we put our annexe up once in five months. The jayco should do most tracks providing a little common sense prevails, right speed, right tyre pressures, right loading in van etc. P.S. make sure the damn fridge door locks and don't take any bloody beetroot!!!

Hi Andrew. I asked this exact question a few weeks back and got a few positive answers. We are taking a Flamingo, (we win-we have 3 kids!). I don't know if you are aware, but you can have independent suspension on the camper for $770. We were not told this, we had to ask. Enjoy your trip.
