I picked up my expanda last week as well and it only came with the rear gas point after asking for one front and one rear, local dealer fitted the front gas point when they did the pre delivery check, also came with two gas bottles . West Aus.
We have 2 bayonets fitted and have used both at various times due wind etc.
Van built Nov '11. I have asked Jayco directly for the applicable regulation twice now to no avail. I have asked a registered gas fitter who looked in the Vic regs and could find nothing to prevent it.
