Welcome Aussies1129! We ran into several Jayco owners while visiting Australia last October. Although due to different materials used to build the trailers sold there in Australia than here in the Us/Canada, your Expanda (we call them Hybrids here) may have issues that North American Jayco's owner may not have experienced. Check in with us every now and then and let us know how camping is going.
When you get a chance, tell us more about some of your camping experiences there 'down under'
