We use the regular SS pressurizable version. Not the Westy sized one. Works
perfectly, stores in the underseat compartment. We heat it with the external
propane stove that is part of our camping issue.

This, the inflatable shower curtain, the slatted wooden utensil carrier (to
stand on during the shower taking process), and the 12 V hair dryer
contribute to the peaceful and tranquil outlook of she-who-must-be-obeyed.
This in turn exponentially increases the enjoyment of the excursion.

Oh yes, by storing the Zodi unit on the passenger side, I am able to reduce
the differential tilt of the Westfalia.
