Actually one of the handiest little camping gadgets we've got is a collapsable sink. I think it was made by Coleman, but its basically just heavy duty plastic in the shape of a double sink with some support beems and handles that folds down basically flat when its not in use.

And a wagon should absolutely be find for camping. With two people, even a sedan can be used quite easily, although some things often have to find their way to the back seat.
