If I were to get a full-size pickup AND money were not a factor, I would get a Nissan Titan. It is a 1/2 ton with the towing capacity of a 3/4 ton. It has more hold down options in the bed than you know what to do with and is available in king cab and crew cab editions. The only problem is that it's in the $30k range, and that's too much for me. I would rather spend $5k or less on a mean, ugly old 4X4 that I can thrash through the woods with. Something like this:
