Its not so much do you need them as in are you anywhere you can get a start

on my recent trip I had a cd stick in the drive and was unaware it was drawing power woke up next morning and heard the dreaded click click for about 30 seconds I thoughtbleephere I am on a track where no one had been for 6 weeks (checked the visitors book at the border)

then remembered my dual battery system has to have a tweek to set the solinoid and I had my thumper in the back in case and started breathing again I could not even begin to think how long I would have waited for help (automatic) I only had two months food and water

my point is its not only a fridge its those little things that you cant control

The short answer is no you dont. If you want your car to start in the morning then maybe..

then, you dont need to run fridge all night, I usually unplug mine when I lock the car before bed... usually cold enough to keep it good for 1-2 nighter doing this

I reckon you need two boxes of electrons if you go bush, especially one vehicle, irrespective of what the fridge needs. Or if only one battery, then two means of recharging it, eg. 2x solar panels plus the alternator. Then you are less likely to be a victim of the one flat battery and no idea how to get mving syndrome.

One is OK, but 2 is better.

If you have been running the fridge for a while and it is down to temp and you keep it closed, then an overnight stop should not (under normal circumstances) be an issue, however 2 or more nights then you will have an issue.

Strictly no, but duals are defintely better than not. We have an Engel 40L running off a factory GU battery and have had no problems but also have a Projecta in line low voltage cut out fitted ($20 a KMart) and carry a jump starter pack as a back up and to run the camp lights if the vehicle is away.

People do, but I personally wouldn't. I'm pedantic about batteries... I panic when my aux battery goes half lat! LOL

That's why I've got enough battery power under the bonnet to start a kenworth. LMAO.

no you dont need dual batts.
i'm fitting duals right now but have used one batt for several years with only 2 flats.
lots of things to consider, are you doing enough kms to charge your batt daily.
are you with people who can jump start you.
cold winter or desert nights when you can turn the fridge off.
turn it up high for last 1 or 2 hours of driving.
my impending dual batts will let me sleep better and reduce my intake of red wine.
