Wiring is marginal for DC.  Fuse holder/fuse must be clean.  Connections
must be good.  Fridge only starts cooling after 20 minutes or so, and stops
much quicker than that.  No good for stop-and-go.  Fridge works less
efficiently when the van is moving no matter what the power source, as the
motion of the van disrupts the gravity flow of the liquids and gases in the
cooling unit.

Sure, just get a regulator (Marshall Brass 290) and attach it to a BBQ
tank.  Use a length of approved low-pressure gas hose (RV dealer) and get
fittings at the hardware store to mate the hose to the fitting on the rear
of the fridge.

It goes to the LED panel.  It's connected to the thermocouple that senses
the presence of flame, and is used to light up an indicator on the LED
panel.  It has no effect on fridge operation unless you ground it.
