BCA Transporter drivers and Cool Boxes

Hey Guys

I was wondering do you guys have mini fridges in those cabs or do you have to use cool boxes ? Secondly if you have to use cool boxes how do you keep the food cool overnight when you have to turn the power off?

You leave it plugged in,and switched on,they draw very little current.
If your worried, just run the motor up for 10-15mins,before bedtime.
