Hey bought 2015 suburban and trying to figure out if it has tow package! It has the tow haul mode but Doesn’t have the adjustable grain for the brakes? Also has hitch with 7 way plug connector from factory. Also has 3.08 gear ratio but when I look vin up it tells me min is 3.08 to the 3.42? Can anyone help me see if I do or don’t?

 

Google RPO codes for your truck. RPO codes are what was installed at the factory. Sticker is in the glove box and if not there scan the QR code in the driver's door jamb area.
I don't know exactly what year they went to QR codes.
RPO codes on GM vehicles are its DNA.

 

Our 2011 Yukon XL Denali purchased 2021 has every conceivable option except the electric brake controller Had to have that added.
