Rather than fitting dual batteries I am considering installing the biggest deep cycle I can fit and using this to start as
well as run the fridge and lights when stopped. I have a genny as a back up should I flatten it too far.
How
well will a deep cycle operate as a starting battery (petrol V6)?
Jim.

Jimbo, I'm currently trialing a system similar to what you speak of.
I've fitted two 115 amp hour Trojan deep cycle batteries together in parralel with no isolating system. Sorry to say Ozguy & TheUndertaker but its lasted over a year so far with no hint of failure & I've never had any battery spin the 1HZ diesel over quicker.
With 230 Amp hour on tap it has run the fridge & lights up on the cape in 34 degree heat for 4 days & still started.
My theory why it works is that the 2 batteries share the high starting load. Fitting one standard 80 Amp hour Deep cycle as a starting battery probably wouldn't work as it could have trouble delivering the starting current & may cause damage trying.
As I said earlier the system is on trial & I'm currently doing tests to see whether the car is actually fully charging the batts. I suspect not but even if it only puts in 80 % that's still over 180 Amp hour to play with.
If you only want to use one battery I'd go with some of the other advice and get a big cranking compromise type & fit the Low voltage disconnect then use the genny as back up . Cheers Craig................................
