Hi all
We are in the same position (need room for 5)
I rented a Kimberley Kamper with kids room first, and it wasn't quite big enough unless you used bunks.
We then rented a Johnno's with kids room, it was ok but very basic.
We decided we wanted the kids on stretcher beds and not have to climb over each other to get out of main bed.
We ended up buying a used Cameron Camper with kids room.
It sets up pretty quickly, takes just as long again to put up kids stretchers!
When I was looking I also liked the Tambo Omeo and Complete Campsite with XT (extended) tent. They had plenty of floor space in tent and the walk up bed.
Not many Omeo's around, Complete Campsite hold their value and not much to choose from in FNQ. I was prepared to drive to pick up but found ours locally.
We are happy with it, there are always compromises.
