It's ammonia, hydrogen, water, and a suspension of  sodium chromate for
anticorrosion.  The suspension stays in the bottom with some of the ammonia
and most of the water unless it gets baked onto the boiler walls because of
operating at too great an angle.  The hydrogen, ammonia and water vapor
circulate around in various interesting ways in the upper parts -- there's
a good description and diagram at www.rvmobile.com/ .

Dometic recommends that before replacing the fridge in a vehicle it should
be tilted in each direction to avoid any pockets of liquid  in the wrong
place that might slow down the initial operation -- but there really isn't
any possibility of anything needing to be redistributed to the top of the
fridge because of it having sat in operating position for a long
time.  What goes up is gas and vapor, and it condenses or liquefies and
comes back down again as part of the cycle.
