We had 5 kids to fit in our car etc, with a 12 yr age span (youngest is now 19, so longer an issue). We had a Ford wagon with a Take 3 seat in the back, and although camping trips could get squashy, we managed to fit it all in. We would camp for 2 weeks at South West Rocks every Christmas and would tow a Southern Cross camper trailer. Everyone managed to fit in, along with the Chrissie pressies! It just takes some organising.
