Hi, we are a family of 6 (kids 9, 7, 6, 3) are will be caravanning around the East half of Australia for 3 months from around July this year. We are looking at the Jayco Expanda caravan model 21.64-1. Would love to pick one up pre-loved or even hire one because I don't think we will be keeping it after our trip. We have a Landcruiser Sahara so we have the towing capacity. We liked the 21 foot model because of the separation between parents and kids and the second table configuration to separate children while doing school work. We have never owned a van before so open to all advice and tips.
