Are any of you guys running dual batteries on your Sierra Denali's? I'm wondering where you ended up fitting the second battery? There's not much room under the hood. The only spot I can find is under the passenger side hood hinge, but that location looks too shallow for a battery to fit. Any pics would be great!

Thanks.

That's the location for the 2nd battery on diesels - but there's a 2 inch body lift on them too which may make more room depth wise - why do you want to put in 2 batteries?
