I too like the vehicle based touring set ups..
someone mentioned above about the fridges in the back of wagons here how I did the 100 series as its just gunna be me the Mrs and little guy.
a ply board fits in with 2 40ltr engles side by side .
We are deciding on a tassie trip also for dec/jan 2015-2016 and thinking of the awning set up I am leaning towards having some sail track rivereted onto the roof rack and some custom made canvas pieces that simply pull through it.
I watched a guy set up in minuts and he had plenty of space under cover without a massive awning on the side of car. He said and I agree that the wing awnings are great ..just not quite big enough to give shelter in rain ect. he said he spen $100 on the track and fixtures also got it powder coated to suit roof rack colour and $450 at a trimmers for the awnings. he had a rear one and a side one which also has a trinagle piece that zipped in for bad weather ..I wish i had taken a picture.
This is what I am thinking of doing .. it did require 6 poles to be put up but he was done in no time and had a bloody massive area. It also packs away separate from the car ..he just pulled it back out of the track folded it up and popped in a bag and he was done.
I aslo recommend the boab 42ltr foot well tank..ours has been around the traps and is still going fine and I stack full cartons on top of it.
