I think if she's used to the car and long haul drives, then she'll travel fine. Our longest trip was from Melb to Adelaide - we only had to stop twice, for breakfast and lunch! She was almost 2. We did a five hour drive when she was 8 months, she traveled fine until about four hours in. Then we just stopped, had a nappy change and a breather, and we were on our way again. We also did a drive to Mildura, so took us just under 7 hours, and again, she traveled without a hitch.

We've slept in both a tent and a camper. She's fine in both, absolutely loves it. If you guys love to go camping, I wouldn't stop. We have a dvd player in the car that only comes out if she gets restless (so the novelty doesn't wear off), and she'll happily watch Play School as we go. I think the earlier you get them used to long drives, the easier it is for them and you, and the further you can go!

Enjoy!
