I always start my trips with a big bucket of ice in the fridge the day
before and I turn on my computer CPU fan that is inside the fridge. Coupled
with about 24 hours of 120v operation and the contents pre cooled that I put
in there it works pretty good and will freeze the munchkin ice trays once a
day even if I open the door a few times.
You need to check the fit of the door seals since they get hard and leak.
I carry a good co0leman cooler with bags of ice and better still are the
Omaha Steaks or Honey Cure Ham styrofoam shipping boxes to keep ice for
about three days.
