Dual Battery for D-Max

Under the passenger seat for the compressor.
I was flat out getting my dual battery isolater under the bonnet. Still think it's the best ute I've had though.
Just towed a full size toyota huski 8 bobcat home on a plant trailer to get it out of the floods - we were evacuated from Pinkenba at 1000 am. Not something I'd normally do but some dingbat (me) damaged the truck last week and it's getting repaired. I'm impressed with how the ute handled it (and stopped it).

Hi GBC
Isn't it noisey in the cab when you activate the compressor/Locker. I have one in Pajero under the bonnet and it is quite noticeable when I use it.
I was also looking at the idea of using the Air Locker compressor with additional fitting and flow sensor to reinflate tyres, rather than carry an additional compressor for this. I don't think this would work too well under the passenger seat.
I presume you have lockers in your D-Max. Was this done by ARB, and is this their solution to locate the compressor?

Mine's a colorado. Yes, it's noisy having a compressor in the cab, but given the amount of time it's activated, and the amount of protection afforded to the machinery, it seems a pretty good compromise.
Nil lockers on mine but that's how the collie's are done.
I had an incab compressor in the gq that I used to race - you get used to it like anything.
I ran lines to the front and rear with nitto fittings for tyre inflation purposes and used a short length of portable line from there.

You could also mount the compressor under the tray if you were concerned about noise. You would have to try an mount it in something reasonably thief proof though. I had an alloy box bent up for one I had in my old ute, not completely thief proof, but nothing ever is.
If you go and talk to whoever you are thinking about manufacturing your tray, I'm sure that they will have plenty of ideas.
Not sure what area you are in but I have been talking to Obieco at Tamworth NSW who have been very helpful.

Hey Tanka,
I'm in Perth and just went to speak with Unicorn (a local tray manufacturer)
I'm going to rough-up a digram af a wishlist tray to cover all these points, including extra space for an extra fuel and water tank behind the head board ... or replacing the headboard.
My goal is to try and minimise the camper overhang over the rear axle (mid-point of the camper would be ideal), yet still have storage space built in directly behind (or replacing) the headboard.This could then be easilly made theif proof.
