D40 second battery mounting kit?

[nickma]

Hi all,
Have a 2008 D40 2DR single cab Navara tray, Thai built (MNTACUD40......). Looking to fit a second battery and looking at placing on the passenger side near the fuel filler.
Has anyone performed this on their D40 tray back and if so any tips on what to be aware of?
Perfect solution would be a off the shelf battery holder that I can bolt straight on, anyone aware of such and if so would appreciate supplier/brand details.
Thanks to anyone who can assist.
Cheers.

Depending on how large a battery you want im pretty sure pirahna make one that bolts up onto the chassis under the drivers side
