A series of Electrolux 2/3-way van fridges had a "remote" flame viewing
window on the front panel, but it still involved gymnastics to line the
Mk1 eyeball up with its axis to actually determine anything, and then it
was only possible under favourable light conditions.

I think that comprised a mirror on a flap which you flipped down to 45
degrees from the vertical so you could look down onto the mirror instead
of squinting at floor level.

A review of our caravan (1978 Abbey Cambridge) made a point that the
siting of the fridge at waist level was convenient from the POV of
viewing the flame.

Our fridge is just 2-way (gas and 12V) but I've a transformer that runs
the 12V heater off themains when we're on a hookup. It actually delivers
about 18V which gives far better cooling than the gas does (or native 12V
would do). However it weighs a ton and I'd love to replace it with a
lightweight smps if I could get one at a reasonable price. If it were OK
with 12V a low voltage lighting 'transformer' (actually SMPS) would be
ideal but I'd need to replace the heater element with a lower R one to
make that work :-(
