Depends on your planned usage.
Even with a fridge/freezer, my big deep cycle second battery rarely hits rock bottom (although I usually don't stay in one place for more than one day).
I do have permanent jumper leads between the main calcium/calcium starter battery and the second deep cycle - large diameter cables with 175A Anderson plugs that I can just connect/disconnect with a minimum of fuss and no risk.
Ciao for now
Andrew who would have trouble finding space for a third under the bonnet.

I think you are talking about the diesel in which case you have 2 options.
1) Move the fuel filter and fit a 3rd battery over the L.h. Wheel arch.
2) Fit a controller between the 2 main batteries and fit 1 High cranking battery and 1 100 a/h aux.

I run a 55A/H Optima Yellow Top in the rear of the vehicle through a Pirahna isolator mounted under the passenger seat
. Has done the job for a number of years running an Engel 40L fridge and sundry 12V appliances including a 300W inverter. Really needs to be charged up each day. I have had it tested and it is OK.
Just purchased a Twozone so I'm looking to upgrade the battery to an AGM of much higher A/H.

If it was my vehicle i would fit the third battery and make this the starter battery,then use the other two as the aux batteries this would run a decent fridge for up to 4-6 days instead of flogging the guts out of one battery.

Also i 've tried different brand trays in the 100 series diesel and found the TJM tray the best.

Nice idea, I will check the main leads on the next one that comes in and see if they will reach the 3rd battery.
You can even use the 2 standard batteries as auxillary until they die and then replace them with AGM's.

I agree the 2 std batteries would last for years!
