GU Duel Battery System with Deep Cycle Battery

This is what I've got and got it a lot cheaper than that.

Good pick up. I got my 120 for under that.
I was quoted $215 for my 120ah, from memory the 105 was around $185.

No matter what tray you get, likely you should also get some fabricating done to stop it moving and breaking underneath.
I had a metal strap/ connected betwen inner battery hold-down out to the guard.

I've put a Delkor MF under my bonnet, I have a GU TB45e and it was a pain in the butt to fit it in, welded up my own battery tray that uses 4 factory bolt positions, had to shift my diff and tranny breathers as well as change the loom that runs into the side guard to the side blinker and aerial.
I fitted a ABR sidewinder dual battery isolator, I've fitted a monitor in the dash that i can check the voltage on both batteries as well as jump start off the auxiliary.
I ran 3 B&S between the batteries which I now believe is way overkill, I could have saved some bucks and went smaller, I ran 8 B&S to the back for my merit plugs, after measuring with a multi-meter there was no voltage loss to the rear. I didn't run an earth back to the battery from the rear and just used a rear earthing point and that has worked fine.
I have heaps of stuff running auxiliary battery and it has been great, have an evakool 70l DZ fridge/freezer in the back that stays real cold, as well as all our camp LED's, front and rear light bars (switched).
If I'm on the road a bit the battery stays charged, and when I'm not using the fridge, most days the isolator doesn't even switch off, when we pull up and camp for a few days I just connect the solar panels to the aux. battery, never had a problem yet and the battery is only an 80 AH.
I use 2 x 120AH AGM batteries & 120w solar panels when we camp out with the camper trailer, and after a few years camping trips have decided that I reckon we could get by with half that easily.
I it was a bit of a rant, but you can spend a lot of money and end up with something that is way more than you need.
I spent a lot of time researching what I was going to do then spent about half as much as I thought I would buying the bigger stuff through ebay.
