Thanks for the many and varied responses.
Looks like something around the 40l mark would do the job and until I am convinced or can convince the family to do multiple day remote area trips then I will probably hold off going for a second battery set up.
I generally run rechargeable led lamps and a gas lantern together with head torches around camp so other than the fridge do not plan on any other electronic devices drawing power when stopped.
Not yet got to the stage or length of trip that would require a hot shower but might be necessary to get my wife and daughter motivated for a longer trip.
Have no particular allegiance to brands so will do my research on them shortly once I have pinned down what I want or need.
Again thanks for the feedback so far, I hope otehr are finding this interesting as well.
I must say I am very surprised at the cost of these, when you can walk into Hardly Normal and purchase a 400 -600 lt fridge with all the bells and whistles for about 30% of the cost of a portable 40lt one ?
With the strong $aud are there any O/S sites you can purchase from and ship in, like tires ?
