see post 13085. similar to Stan i installed the following setup:
Pirahna tray $110 (saves a bit of the mucking around required when relocating the power-steering reservoir)
Exide Extreme 12" (86EX i think) bty $135
Redarc SB112 Isolator (100A microprocessor controlled isolator) $135 direct from Redarc
2guage 160A cabling (Jaycar) approx $30
2 x 70A circuit breakers (Jaycar) @ $23 each (one next to each +ve terminal leading to isolator)
asst connectors $20 (Middys)
Small fuse box for distributing the aux load (Pirahna) approx $20?
= total approx $490

Only minor thing i'd change if i did it again was looking for a battery that had the same terminal post configuration as the primary battery so the batteries were interchangeable. ie: if i do need to put the Exide Extreme in the primary spot the primary cables aren't long enough to reach the Exide battery posts. (I see from Dereks photo that the aux battery he has used has the same post positions as the primary bty)

I also have a 2005 Prado and have done a fair bit of research on this topic. If you stick with name brands which seems to be confirmed by most people on this site you can't go wrong. Recommendations are to go for either Pirahna, ARB smart solonoid system or Rotronics. As far as batteries go, if you can afford an AGM battery they are definately the way to go (especially for running fridges, they have deep cycle battery characteritics with the quicker charging rate of a standard battery) I have looked into the Fullriver brand of AGM batteries and these seem to be quite good and feedback from others confirms this. I'm hoping to fit a 110amp hr battery under the bonnet and am in the process of checking whether it will fit, where it will fit and can the panelling under bonnet take this type of battery weight without additional support.
