With the design of modern 4wd there seems to be no room for an auxillary battery in the engine compartment.

Whats the best and most cost effective method of being that allows a fridge to be run in the vehicle when stopped and still not run down the only battery.

Cheers,

Cruiser

G'day Cruiser,

I had the same problem and ended up fitting a battery box in the back right beside the fridge with a 40A dc-dc charger bolted on top which also charges my caravan batteries when hooked up. when we are stopped the Redarc charger isolates the aux battery which is then charged by the solar panels on the caravan.

it works well that way for me.

Until you get something sorted it may be worthwhile running the 12V power to the fridge through a monitor which switches the power off if the voltage drops too far.

Like this: Battery Protector Cig Plug one from Jaycar.

Having had fourbys with dual batteries forever we ran into a problem like yours when we decided to purchase a Jeep Wrangler.
Our solution was to buy a Thumper (we went for 105Ah version) and got the wiring for it done properly by a 4x4 place (anderson plug to connect to battery etc).

We ditched the Jeep after about a year but kept the same system after getting a Troopy (just had it wired to suit), this way we can take the fridge and thumper out when we're not tripping around and just using the car as a daily driver.

For us it was an easier alternative to getting a battery box and figuring out the right set up, although I'm sure Hubby would have been more than capable. Lol the Wrangler was quite a PITA, took them ages to find the right wires to wire it up!
