Depends why you think you want a truck. Obviously to be able to haul stuff, but what?
Most people can get by with a 1/2 ton full sized pickup, which usually handle a payload of about 1000 to 1500 pounds. Some people are even happy with a mini pickup, which are limited to much smaller payloads.
If you think you'll want to haul more, or be able to pull a sizable trailer, then you'll need a 3/4 or 1 ton pickup. These will have payload capabilities from 2000 to over 5000 pounds, and will pull up to almost 12 ton trailers.
In my opinion, if you want a mini pickup, then Toyota is probably your best bet. For 1/2 ton and larger, I am a big fan of the F-series Fords, which have been the highest selling vehicle on the planet for over two decades. I personally own a 4WD F250 Superduty. It has served me very well on many occasions for hauling/pulling, and has been very reliable. However, unless you have the occasion often enough to utilize a full size pickup, and are willing to live with their poor mileage, then you would be much better off just renting one from a Home Depot or Lowes.
