Itis not required to back up, but it will help the truck go back into the 4 open quicker. works on Fords and dodges too. Loaners are a courtesey for the most part. If your vehicle is required to be in over night due to repairs, then GM will provide a loaner. If it is overnight waiting on parts, they do not. Want a loaner from a dealer, be nice when you go in and promise/give good surveys. The service writers get grief from all sides, they can be extremely helpful to you if they are on your side. Although it seems petty to charge to fix little annoyances not covered by the warrantt, someone has to pay the mechanics. Sorry for the rant, but I hear it all day.
