My '08 F250SD is scheduled to be delivered 2nd week in May, the dealer says they can arrange to get the gooseneck hitch installed and that if something goes wrong with the install they can take care of it. Since the dealer don't install the hitch a local trailer supply place does is there any benefit to arranging this through the dealer (warranty etc.)

I have bought 3 trailers from the same trailer place and they would charge me $475 to install the hitch (a Cody hitch). I have not got a price from the dealer yet.
