Which way do we go?

Hi all,

We want to head from Victoria to Queensland, with the ultimate goal being a cound couple of days on Fraser Isl with kids in-tow. This is a trip that we have often discussed, but (due to costs and inability to arrange time off work) we have not yet made.

Our challenge is to stay off the tar.

There are a couple of reasons for this.

Firstly, one of our group has recently expanded his 4WD and Solar fit-out business to include design and construction of a range of "SERIOUS" off-road campers. These things are beasts.

His goal is to take his base model prototype on "a little drive" through some challenging and varied terrain. The rougher the better.

Secondly, we (3 of us) have worked hard over the past few years to take ourselves from Sieras, and Ferrozas, both of which served us well over the years, to a 100 series Landcruiser with a lift that requires steps (or a 7ft min body height) to enter without straining, a 2002 TX Prado, and a 2003 GXL Prado.

The 100 series has had some work done to it including a lift, OME stabilizers and shocks, rails, etc. However the 2 Prados still behave like shopping trolleys.

I'm looking for advice on 2 points.

Firstly, what would members/contributers reccomend in regards to a suitable route, given that we need to bash the hell out of the camper, but also don't want to spend $$$ on working up the Prados?

Secondly, what "minor" alterations"/"Additions" should be made to the vehicles to ensure that we're not stranded 2 days out of Melbourne?
