I have been wanting to add a dual batter setup for some time. Not for winching (at this time) but for accessories. I recently added a battery management device to my trailer, and thought it would be a good way of managing my dual battery setup too. For the battery location, I decided to find a second tray to put in the factory location. I found it at Stainlesstrays.com. For the price of a new tray for the drivers side from some places, I was able to get two new stainless steel trays. The original one was looking a little worse for ware.
The new and the old side-by-side
Here are the pictures of the new trays installed.
I don’t have the second battery or management device yet, so I haven’t figured out were I want to put the radiator overflow tank.
