Well over my weekend I decided to work on my dual battery set up. I forgot to take pictures of the actual tray. But it was made from 1.25" angle iron. I will at some point get pictures of the actual tray. I used 1.25" flat bar to fabricate the brackets to hold it in. Top strap that holds the batteries down is 1.25" flat bar with the ends bent down about 1/2".

I used some old military terminals I had laying around. 1/0 copper wire red abd black and soldered on my terminals, then crimped them, then heat shrunk them.

Battery Isolator is rated for 150amps and I mounted it behind the fuse box.

I have to put some heat shielding on the wires running to the battery isolator due to proximity to exhaust headers.

I have two group 34 batteries installed one just a plain NAPA wet 8434 (1050CA) and an Optima I am going to replace with another NAPA 8434.

Plans include TerraFirma heavy load/duty front coil springs, DAP discrete winch carrier, throw in this old 9000lb winch I have had for years. Would like to get a Surco baskcat and put on top with two alley lights on each side, four light pointer forward and two or three pointing aft. I'm keeping my SLS suspention (dont laugh) but using some spacers to give me 2" lift.

what is the advantage od running dual batteries?

1. I can jump myself off.
2. More amps to run high current items (i.e. winch, lights, etc)
3. I'm sure there is more.

If you have a winch, you could use up so much stored energy getting your self out that you don't have enough left to crank the truck and go home. Lights are another issue, becuase the base alternator on a D1 puts out a whopping 100 amps, and a stock D1 with everything on draws about 85 amps. Don't leave much for eight Hellas... D2 a little better off with 130 amp alternator, but draws more amps to start with with all the toys.

Nice job on the in-line fuse holder, so many leave that off and later find they don't like the smell of "truck toast".

Thanks for the info, i am learning and always asking questions.
Where could one find a Battery Isolator?

IS there a difference since I have and 04 D2?

I work for NAPA, we sale them there I can get a part number tomorrow.

OK, thank you,

you can also just look around the web for voltage sensitive relay. descent ones are not cheap.

You have a problem, already, a good 9000 # Warn will draw 450 amps on a hard pull and when running duals, if set up properly, you must have 2 matching batteries both for the draw and the recharge. I don't think that 150 amp system won't cut it.

I think Mike has a point as he uses a dual batter setup and winch..

I have heard good things about this system..
