My father is planning on getting a new truck soon and wants to go on a road trip. He had a good question about what happens if the new truck breaks down 1000 miles from home?

Of course it would be under warranty, so a Dealer say in the Smoky Mountains would have to work on the truck, give us a loaner? Say the engine is cracked and will be a month before the truck is driveable again, we cant stay 1000 miles from home for long, so we would have to drive the loaner back home and have to drive back to get the truck or they ship it by car carrier to the local dealership?
