2016 Tacoma battery options

has anyone upgraded there battery yet besides the simple group 27 one I'm looking for a large battery option or even a dual battery set up found a lot of info on the 2nd gens but nothing on the 3rd I heard we are a bit tighter on space in these new trucks

 

I have been considering trying to put a 2nd battery in, did lots of research, but haven't completed it yet. I drive to northern Canada from Texas once/twice year, and I am in some remote areas, where a 2nd battery would be great for emergency, and generating electricity.

Maybe someone has done it already!

I've been considering getting this if I can get my spare funds setup properly:

Looks to be a nice setup. I haven't seen a dual setup in a 3rd gen yet, but this would be a good start.
