RedArc is a great South Australian company and their tech service and back up is second to none.
If you are in Adelaide, you can also call in and talk to them face to face.
I talked to Redarc tech department before I installed it about 4 years ago the bloke I talked to had one under the bonnet of his own Prado
There is a thread on the Redarc forum now about installing one under the bonnet of a Prado .
