Surprised to see a V10 F250 pulling the Keystone Raptor as I would not be comfortable pulling it with anything less than a F350 DRW diesel based on weight ratings. I have the Raptor and the ONLY truck rated to pull it properly is what I bought. I did have a V10 E350 van and I loved the engine, hated the mileage, loved it to tow my 20 foot boat.
