If you are going to be towing alout of the time then I would go with the f250/2500. A lot of guys on here do it with 150/1500's or even rangers and s10's. While they may be rated for the weight trailers put alot of abuse on the trucks. Not only on the drivetrain but on the brakes aswell. Also going with the 250/2500 gives you more room if you expand and decide to grow.
