This same chassis is used for diesels. They require two batteries for starting. Police package Tahoes also get two batteries.
I've actually converted both of my trucks to dual batteries. My daughter has the one at college in upstate New York, and I don't want her stuck with a dead battery in the middle of winter. We do a lot of camping with my Suburban, so I like the second battery when we're boondocking. Kinda hard to call AAA for a jump start when you're in the middle of the woods. All factory parts were used, so they each have the ignition-switched battery isolators, to prevent any possible drain of both batteries.

I did it myself. Probably $350 in parts, bought online, plus the cost of the second battery.
