Everything I've seen/heard/read about the new generation of GM trucks is that the K2xx series disconnect the trailer batteries.
As wired from the factory, GMT900 and older generation to do not disconnect the batteries when the engine is off.
The K2xx is the current body style, which replaced the GMT900 (07-13 1500s and 07.5-2014 2500/3500)

not true, the My 2015.5 2500HD duramax is just like my 04.5 duramax. the battery does NOT disconnect with ignition turned off.
Some Gasser versions do, but NOT the diesels. Gassers depend on if you have the dual battery option or not.
