With those weights you will want a 1ton (350/3500). With a GVWR of 14950 expect a pin weight of 3700lbs. Yes it could be less but it's easier to plan for the max than worry about it later.
Most of the new 1ton pickups have payload capacities of 4000lbs or more. You will want to plan for 3700lbs of pin weight plus any cargo and passenger weight inside of the truck. I would say a payload rating of 4500lbs and up should get you to where you would want to be.
Which brings me to - do you want a dual rear wheel pickup or not? While you will most likely be able to get by with a single rear wheel setup the "dually" or "DRW" will offer better stability while towing and even greater payload ratings. However they are not the best for "around town" driving.
Best of luck to you.
