That's how I've been setup for the last 8 years or so after my Redarc failed. So far it's been drama free, but I don't setup a long camp or leave the fridge running for more than a day without moving either.

I am just back from an 8 week trip, My ARK Pak did the job! with some on the trip adjustments! I.e. I had a lot of troubles with my disco 3HSE cig plugs and eventually wired the 240 v charger into an inverter and an Anderson plug that was there at the rear
It would keep the fridge a WAECO cool for 4+ days.
Most deep cycle batteries will not like lots of winching but a long jumper lead would let a rear mounted ARK Pak power the main battery?
Hopze this helps.
That's how my 101 is set up and I've been out for 11 days straight now and have had no dramas. When set up for more than an evening, I put a 120 watt solar panel out that charges both batteries. Running a fridge, LED lighting and my ipad and laptop charger. Car has started easily when needed. I was going to put an isolator between the batteries but I don't think I'll bother now as this setup has worked so well.
Just for clarification, I have the cranking battery in its normal home and the second battery in the trailer I'm towing with a permanent 20amp supply running from the first battery. Solar panel connects to the battery in the fridge which keeps the cranking battery charged as well. Happy days.
bacicat,
I too have upped my simple system with a 120W panel and reg.
A few weeks back, went bush and left ute for 3 days. I got back to ute at 930 batteries were at 13.5V engel and beer was at -1. Perfect!
And that is with panel just facing north at bout 45degrees, no chasing the sun.
So a little less simple but perfct for me

Well I reckon the best dual battery setup has a dual alternator as well.
Attached my circuit for dual batt/dual alt setup.
2nd alternator is from a Mitsubishi L300 55 amp, from a wrecker coz the
front shaft and bracket mounts means it fits the original D1 TDI 300 position as well.
can do all this with a lot of mucking around and $200 including battery which is a
Caterpillar deep cycle marine "wet" battery. Runs the 30 litre engel for over 24 hours.
