Issue with brand new truck. Advice on how to proceed?

After the heat of the moment has died down, many new cars come in damaged, and they get fixed without the Buyers knowledge. it is a fact of life. in your case you saw it, but it happens all the time. it is your choice to pursue the issue. Every brand and model.

That does not make it right. A new car should be without blemish, certainly for what you pay for them. A guarantee if you went to trade a new car that had been wrecked without your knowledge they would stick it to you again.

GM used to send the local high school Vo Tech ones that had gotten damaged in transport. When my brother was there they had a 96 Camaro RS, that had been side swiped by a recap blowing off the transport. GM took the airbags out, and sent it to the school. The boys line locked it so much in the parking lot, that they literally burned the rear tires off it.
