Thanks all!
Lloyd, you're right I don't NEED a second battery, but a lot of our trips are 5-7 days, and with the "gadgetery" we take with us nowadays, video cam, GPS, dig cam, CD player,blah blah blah, the fridge has tipped the scales.
(Remember when camping was Beer, Rod, Axe, Tent?)
The other thing is, this is the first AUTO 4WD I've had, and it has allways concerned me that I can't pushstart the bugger.
I've had fasteddys' experiences a couple of times <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> , and luckily, had a jumpstart available.
So, I'm going with Craig and Fasteddys advice, and installing a deep cycle second battery, for the accessories only.

Tim, thanks for your input, but I was allready sold on the second battery, just wanted advice on "how to".

OT: Craig, so......... your Missus comes from Vic, and your batteries don't last so long, hmmmm, I would think about this for a minute...Just a thought <img border="0" alt="[Hillbilly]" title="" src="graemlins/notooth.gif" />

I think I'm gonna pay for that <img border="0" alt="[Ignore]" title="" src="graemlins/ignore.gif" />
