What works best on my Westy Refrigerators is:
Pre Cool the night before with 110 v or Lp fuel.
Put a can of ice cubes or pre cooled aluminum cans of drinks in the box.
Install a little computer CPU fan with the heat sink up high on the wall
or roof area on the interior of the box (use double sided 3 M tape). 12v
dc runs on your car current.
Fans in the rear might help but I never had to go that far to get my
munchkin ice trays to freeze.
Conditioning the fridge before you leave is the single most important
thing I've found to enhance the abilities of the fridge. Once the
interior temp is brought down the unit has no problem maintaining it.
Without this pre conditioning it sometimes takes 12-20 hours to freeze
the munchkin cubes, with the computer fan, can of ice it will be frozen
in less than 4 hours. Your fridge will be at about 42 degrees or less
within 2 hours. Once the temp is down remove the cvan of half melted ice
cubes and stock your fridge.
Strange but true.
