Troy:

Your experience, mine, Harold Teer's, make me think
that the position of the temperature sensing thermocouple
makes a big difference.  Other variables, unknown, are
whether the drip pan is installed and whether a fan
is being used (like a Fridgemate.)

I experimented some and decided that the drip pan
(under the freezer compartment) should be there.  All
old fridges that I know had a similar pan, so I assumed
they'd figured it out.  Although I was a late comer to
the Fridgemate in the Dometic, I converted after I saw
how much it improved cooling.  But in the Vitri, I
decided it was better without it.  Active cooling vs
passive cooling, whatever that means....

Vitris should all be apples, but I guess we have apples
and oranges....

BTW--I don't think anybody disgrees with what started this
all--that a week on an aux battery is wishful thinking.
