American Truck quesiton

I am going to be buying a used (because I cant afford new) Full sized pickup, it needs to be able to haul up to 12k lbs and do a 4400 mile drive.

I rarely look at american trucks (dodge, ford, chevy etc) but I think I will need one of these, but I dont know squat about them.

Which has the capability to tow that much weight, be reliable for that long of a haul, and in all honest be a fairly comfortable ride because that drive is going to suck.

Any direction would be appreciated.

Few questions
What you looking to tow?
Gas or Diesel?
Gooseneck - 5th wheel - bumper pull hitch?
Regular cab - Extended cab - Crew cab?

For me when it comes to a pickup truck have always had luck with Ford ....Now my Brother is a Dodge man lol
