For those who have never seen the rare early P22 West interior there is
one for sale on Ebay right now with photos, though somewhat fuzzy.

The P22 has no propane. Thus no stove and no true fridge. It has a
stainless sink and an icebox style "fridge" that require blocks of ice
to keep stuff cold. It has a 10 gallon water tank that fits under the
bed. One advantage is that is has a full width bench seat and so a wider
bed for sleeping and more comfortable seating for just hanging out in
the rear. It also has both tables and the standard poptop with bed that
full Westys have. Not a bad setup for many people but I like the propane
models myself.

A friend of mine and I converted one of these to propane by installing a
Westy 3 way Dometic in place of the icebox and mounting the Westy stove
in the stainless sink top next to the sink. A sweet setup that I have
since seen was a factory layout in some European models. He still has
that camper, done to a Wolfsburg Poptop Syncro, 1986 model.
