Keith,
depends on how long you are going for ?
If it is only a week, no need for freezer...IMO. We didn't take a Freezer on our 8 day trip recently.
Eskies worked well and the Cryovac got a work out. Plenty of ice the various shops around the traps.
We had a Drinks esky.
Meat esky
other food esky
and a large esky we filled with ice at Rainbow. we then used a rotation system. Kept eskies out of sun and only opened them when required.
I think it was day 4 or 5 , before we replenished some ice stocks.
So my question is probably " what goodies do you need to keep frozen " ?
cheers Phill
