We have done a few trip since buying our 16.5 Jayco expanda both free camping & caravan parks. We are about to endeavour our first real big trip across the Nullarbor from the coast of Southwest of WA to Halls Gap in Victoria. Tug is a 2003 Holden Rodeo 3lt turbo diesel.We would love to here any advice from other travellers who may have done this trip. We will have 3 kids in tow 8, 7 & 3 so gaining some knowledge of what is install will be great.
