Is this the standard Redarc mounting bracket or something else? I like how this is installed, allowing for better circulation than inside the engine compartment.

I am thinking of adding a Redarc BCDC1240D to a truck to allow for solar connection when camping since we will be running a fridge 24/7.
Thanks!

I decided to make my own bracket out of 5052 aluminum . I basically took the idea and tweaked it for a U.S. vehicle.

Not to sound like a moron or be repetitive, the one in the pic that I quoted looked like a manufactured bracket that was coated black. Maybe you coated your creation but just wanted to be sure that we were talking about the same bracket.
Thanks for the clarification.
 
I went with the Redarc BCDC1240. Mounted on top of the engine bay fusebox:

No worries, yes I made it from scratch.

I ran 1225D with the second battery kit from Slee with a Slee Redarc Mount. Fits just fine. I was gonna get the 1240D until researched it up on the Redarc page. 1225D can do up to 200 AH, beyond that 1240D is needed. Too much charging current = heat -> battery life expectancy.

I ran the HKB diode with a single AGM. It killed my NorthStar group 27F. Switched back to cheap starter and Redarc with an Odyssey group 35.

I was wondering what setup required the 1240D. I have seen this unit on multiple trucks.

As far as I can tell the 1225D should be able to handle just about any aux battery setup on these trucks. I imagine the 1240D being used for larger battery banks in RVs, etc with >200Ah battery capacity.

You are correct. I was wrong on the model number... I am looking at the 1225D, which for these trucks is sufficient sizing.

Not only that, but a higher amp draw (40-50A) at idle will really stress the alternator. I nearly opted for a 50A DC/DC, but once I started to understand how much heat this can create in the alternator without an active temperature sensor at lower output speeds I went back to 25A.

This is a good reference video:
