Hi all,
I have a fridge for the lorry, which draws about 3.5 amps at 12v (42W). Would you leave it on at night, or turn it off? The truck is a 6 month old Actros, with decent batteries, so I can’t imagine I would have any problems, but don’t want to tempt fate. At the same time, I don’t want a load of ruined food.
The way I see it is, if I left the sidelights on whilst parked in a layby overnight, I’d use more power, so should be fine. What does everybody else think?

Leave it on. All will be well, I promise.
I drive a 58 daf and leave it running all day and night never had any problems
If you drive a fridge lorry turn it on and leave the stuff in the back after you have switched it off. left my stuff nice and cool saves spending money on a fridge
Brilliant, thanks peeps. (If you should happen to see a silver actros with flat batteries this week, take pity on me!)
Micky - sadly not - curtainsiders mostly with the occasional flat.

Leave mine on all day and night, just don`t forget to switch it off on Friday night, Monday morning 
I only turn mine off on a weekend. With good batteries shouldn’t be a problem.
switch mine off at night during winter,but leave it on overnight atm
Original? Leave it on year around. Heater + inverter + fridge at -20c in 9h with good batteries are no problem at all. With temperature on the + side of 0 15h is no problem. Just the fridge, well a week at least works fine and it will turn of automatically when the voltage drops to low.
