Lots of good advice, and some opinions above. I emphasise those who suggested working out what you want to do with your CT before buying it. Long stays at caravan parks with 240v and water vs free camping near Dargo or way up north. Once you've figured that out then you can narrow down options based on price. A Swan is fine for caravan parks, but are not built for lots of corrugated dirt. Build quality can be iffy but they have good back up if something does go wrong - on a new one anyway. Find a leak in your 10 year old roof join and they won't care (post 2007 have single piece roof).
If there is only 2 of you your choices are much wider with soft floors, rear folds, forward folds and a myriad of other 2 birth options. 2 kids is ok but 3 kids narrows choices substantially hence we are looking at either a Complete Campsite Uluru/Kakadu, or more likely especially given where we live, a Mountain Trail Escalade with a 10 foot tent. They pretty much compete against (copy) each other - when one comes up with a good idea it soon appears on the other. Both absolute quality. We have looked at the Swan but would have to put the kitchen on the outside as we want to camp, not caravan (ever see those people who rock up at a campsite in their $80k van, hook it up to water and power, go inside, close the door, turn the air con on and stay inside for the whole weekend.....why bother?) by which stage we will be getting close to the price of the other two anyway. Both will carry 500kg more than a Swan (bikes, kayaks etc) and I suspect a Mountain Trail will cope better in the High Country too esp with its Webasto heater:D
