advice - which camper for a family of 6!

Hi all

I would appreciate any advice from experienced campers as to which camper would suit us best. Some background follows:

We would like to take the family to the tip of Cape York from Melbourne for about 6-8 weeks. We have 2 teenagers & 2 younger kids. We have a 100 series Landcruiser. We are thinking the best thing is to buy a camper van for adults to sleep in and a tent for most of the kids, hopefully then everyone has a little of their own space when we stop for a longer breaks. This is important as my wife reckons the kids will drive me crazy & is not as enthusiastic as me! We also think the van needs to be real a offroader, strong & good resale.

I have looked around a reasonable amount but not sure there is a right solution for us yet. I like the TVan but think it only has a very small & wonder how to cook for 6 on that and also where do people put all their food on that model, isnt it painful unloading everything from the bed each time you stop?

Any recommendations/advice would be appreciated

I am really looking forward to seeing this part of Aus

thanks

David
