A quality 8/9/9,500 lb rated electric winch will be plenty for a 1/2 ton pickup. Learning how to use the winch safely and effectively (rigging) is very important.
For budget, shop around and get the most for your money, buying the best model while sticking to a name brand (Warn, Ramsey, Superwinch.)

I had a warm 8000 on mine with synthetic line with a hidden mount. You want to go as light as possible. I did not use the truck for rock crawling and the 8000 was fine. I had a pull pall and used it to get out of snow and pull other people out. I would not expect an 8000 to pull a fullsize out of it was burried to the frame in mud but that was not my use of the truck
