running 3 way fridge from tow vehicle red anderson plug

HI - so I can run the fridge on 12 volt whilst the engine is running and it won't run my car battery down?
When I am stopped it will be on Gas
it would be disconnected to the red anderson plug on the car manually
thx in advance

If you are stopping for an hour or 2, the fridge will stay cold just like an esky, I only use the gas overnight.

The red Anderson plug was a recommendation by Al-Ko to supply their ESC if it was fitted in your van. The reason for this is that the Al-Ko ESC units can misfire when you are travelling in off-road tracks. It has become a bit of an informal caravanning standard. There is no regulation to stop you from using it for other purposes, however if I was doing that I would change to another colour for use with a fridge.

Regarding the use of an ignition switched relay in the line, it is recommended by Electrolux (yes that far back) as a safety measure. The world is full of good intentions. There are also a huge number of those with good intentions who forget to disconnect the fridge when stopping for a rest stop. Many of those require assistance to restart their tug's motor. There are also who forget to reconnect the plug and lose the benefit of fridge 12V operation during the next phase of the journey. Again the choice is yours.

Thank you :-)

There are a number of variations of stability control these days, but the ALKO ESC version we had on our 2013 Jayco van, tandem axle, applied the braking to all 4 wheels constantly when activated.

It only happened to us twice within a few minutes on a very rough and winding bitumen road and you definitely knew it.

thank you, that was great

thank you

thank you that was good info
the van battery is the 200ah mentioned
how do i check how much power the vehicle is supplying?

I'm no expert others will know more but I like to keep things simple so hopefully less problems.
You need to find out how the battery in the van is being charged wether it's wired directly off your vehicles starter battery or if there is a lithium battery charger it the set up which is the more likely scenario. If there is a charger the amp output should be written on it which could be somewhere between 20 to 40 amp for example. It should also have a built-in battery isolator so when the cars engine is off the 2 battery are isolated so if you accidentally flatten the caravan battery it will have no effect on the cars starter battery.
You also need to know the size of the vehicles alternator so you don't exceed it's limit best to stay well inside it. It sounds like a bit unnecessary and maybe over whelming but it's not that bad and can save you a breakdown in the future. An auto electrician might be able to help you should try and add up within reason how many amps everything will be drawing off the alternator from lights to battery charger etc etc which can be a bit difficult with a modern vehicle but a ball park figure is a good start.

Thank you, lithium battery charger in van is 60amp

That's a pretty big charger it will recharge the battery fast so short drive of a few hours shouldn't be an issue but I still would make sure your alternator is going to cope with putting out that much power and still be able to run the vehicle with it's accessories over the long term .

ok - Thanks Batt

Vehicle alternators are self-regulating. If you attempt to draw more than their regulated capacity, they will not deliver it. Get yourself a voltmeter that plugs into a lighter socket, if the alternator does not deliver the full charging voltage with a DC-DC charger attached, look to see if there is a way of throttling back the DC-DC charger. If you can not set the output regulator of the charger to deliver less current, then you will have to find other accessories to switch off or replace your charger.
