They're not power extend, and considering it's only a midyear update....I'm gonna say it will most likely be plug n play. I bet you won't have to change anything if you currently have the power folding mirrors already.
Apparently, there is a lot of controversy about this and only time will tell.
As of today,
GM Online Order / Reference Guide states ...
"NEW! Mirrors, outside heated power-adjustable vertical camper, memory equipped, upper glass, power-folding and
manual extending, chrome."
As of yesterday,
GM Online Order / Reference Guide stated ...
"DQS, NEW! Mirrors, outside heated power-adjustable vertical camper, memory equipped, upper glass,
power-folding and extending, chrome."
This truck
New in Jacksonville, NC at Moore Buick GMC is advertised a being optioned with ...
"DQS MIRRORS, OUTSIDE HEATED POWER-ADJUSTABLE VERTICAL CAMPER, MEMORY EQUIPPED, UPPER GLASS,
POWER-FOLDING AND EXTENDING, CHROME."
Maybe someone on this forum who actually works at the plant can confirm this one way or the other unless a DQS truck has actually hit a dealership. Anyone?
