Thanks Guys, Hardware is w/o a doubt the hardest to settle on. There is so much crap out there. The slides I used are all 500# Knape and Voight sourced from the internet, I cant remember exactly where but a search will find you the best prices. I do have to say, I wish I went with the much more expensive Accuride drawer slides as they have much better locking tabs. All in all, I am happy w/ the K&V slides.
Yes my Aux battery was added into the driver rear compartment and the stock battery is under the floor of said hatch, accessed through a floor hatch. There is JUST enough room to fish the stock battery in and out through the hatch when needed.
