I'm wanting to add a house battery to my 08 Tacoma 4 cyl for worry-free engine-off lights and music in woods and am currently planning the wiring scheme. Something that's troubling me is the location. I see a lot of people running twins in the factory location rotated 90* using an aftermarket dual battery tray, but they all seem to be designed for identical batteries and most people seem to be running twin dual-purpose starting/deep cycle batts like a couple of Optima Yellows or similar. Is there a reason for this? Isn't a better option to run a regular starting battery and a true deep cycle with a solenoid that only closes with key-on? Is there a tray that will allow for the rotation of the factory battery to make room for a true deep cycle that is presumably a different size/mfg? Just curious how others are running this particular setup as I'm under the impression that a "dual purpose" battery is not ideal compared to a true deep cycle. I'm prepared to build my own tray just thought I'd ask.
