Anyone here running a dual battery setup?

I've been using the Hellroaring system in multiple vehicles over many, many years and I can't say enough good things about it. It is not the cheapest option but I've found it to be extremely reliable and easy to install. You could build a less expensive system using a Cole-Hersee relay, but the solid state system with install kit has been worth it to me.

I purchased an aftermarket battery tray rather than hunting for something from a diesel or similar in the junkyard and it went in without trouble. The Hellroaring system provides me with peace of mind when I park a rig in the boonies and then don't return for many hours or even sometimes days. The auxiliary battery is being charged while driving but becomes fully isolated by the solid state diode when the engine is off. It is a great comfort to know the engine will turn over when it counts.

I'm installing a winch and also want an auxiliary battery in case my main battery goes bad. I'm not sure what is the best setup yet. I would like to use the factory battery cables and make it stock looking as much as possible.
