Alternator upgrade ??s

I like the Denso but also a bracket is needed .
My total draw at idle is 115 amps .
I checked with Powermaster, AWESOME customer service !!
Make a one wire drop in for $280 that puts out 120 Amps at 1000 RPM .
The tech said One wire conversion consists of a 4 gauge to the starter and a 4 gauge to the engine block. Then remove the external cowl mounted factory regulator . Available at Summit #48529-104
I had read that one wire alternators do not produce at idle but Powermaster told this is true of the Chinese Junk one wire alternators. Powermaster is a different design
Any thoughts on the Powermaster One Wire Alternators ?
