Hi Lindsay
I always pack my fridge if I am going on a long journey. You can put your milk in as normal, put your meat on the lower shelves and salad in the bowl, I usually make sandwiches and put them in the fridge so we can have a snack en route! I put frozen meat in the freezer compartment and it has always stayed frozen, fresh meat is also fine in the fridge area. It all depends on how far you are travelling, we went to France in July for 3wks and I stocked my fridge with meat etc, it was fine, even on the ferry for 6hrs it stayed cold, a good tip is to freeze milk before you go and put it in the fridge it helps to keep food cold, try not to open the door alot when you are tavelling as this can affect the coldness of the fridge. Make sure you put your fridge button to the battery operation when you are travelling as your car should charge the fridge up depending on the wiring of the electrics? Hope this helps you?
