As an old yachtie to, welcome aboard. It all depends where you want to take the Penguin, the GRR yes to Mitchell Falls, let you know in a couple of months. We are buying a Jayco OB van after the Kimberley trip and know it will do what we want, nothing like the GRR or the Cape. All campers, CTs are a bit like sailing, you know when to ease the sheets to make it a lot more comfy if you want to be able to use the camper like your trip around the world maybe a campertrailer like ours, it is all horses for courses as they say.
