Ok, thanks everyone, will reconsider.....auto electrics is something I struggle with (connecting stuff is one thing) understanding is completely different....will take advice and go the RedArc dual...

Really appreciate everyones input and assistance...

I looked at the Intervolt unit, still to complicated...RedArc seems to be proven....

Since I will have a few twists and turns to fit the RedArc, what is the minimum cable that I could use that would still enable cranking as well as to be easy to manipulate around the engine bay....
