Keep your eye out on the 2nd hand market. I got a Downunders Camper with independent suspension, full annex with 2 sets of zip in walls (solid & midgy) & another awning over the drawbar side, door kitchen (I'm planning to remove it & make a slide out) 2 x 105Ah AGM batteries in the integral front box & a 60l ARB fridge on a slide for $6000
The fridge & slide would be $2000 by them selves.
I'm 7 weeks into a 9 week trip around the big island & loving it. We drove through Woolongong today.
