GM varies. The 6.6 diesels do NOT disconnect power. Gassers vary, I don't recall what my manual said exactly but I believe vary based on if you have the dual battery option or not.
Thanks - this is good to know. We rarely overnight without shore power and the dual batteries in the truck have a lot of amp-hours - but it takes a lot of cold cranking amps to start that diesel in the morning, too!

That was always my concern with my former Duramax, man,you need lots of battery(s) to crank that engine over even with two batteries.
