what ever part he is waiting on
you never know, my dealer did that for my but it wasent as major as let says the generator, and also they knew the replacement part would arrive about 10 days after, but i agree that most dealer will not do that
Depends on the dealer and how major of a part it is.
Because they are putting the replacement part on a new unsold truck, and likely not testing it and just assuming it works.
If it was a serialized device and FCA found out someone replaced it on a new truck and used someone else's part they probably wouldn't be very happy and could even attempt to void the warranty on the other vehicle they took a part from.
Think like updated part numbers. Most parts have a new replacement part number not the OEM number. So if something broke and was replaced under warranty with the "wrong part" and it broke again FCA could deny the claim claiming the wrong part was put in.
I would just say it's an area a dealership isn't going to want to step into. It's not like they are just swapping a busted tailgate or something. eTorque is an involved technical system with lots of fancy expensive electronics.
