I have little helpful input, but I'll say that I have wanted a TRD Off Road Tacoma for many years. They are perfect for what I need: great off road, nimble, easy to maneuver, haul and tow enough for me, not to mention that they hold their value incredibly well. The Frontier will undoubtedly be cheaper and they are good reliable trucks. My buddy said that his Frontier's turning radius is slightly smaller than an 18 wheeler.
Rumor has it that an all new Tacoma will be released for the 2016 model year. I've owned a Ford Raptor for just over 3 years (I mention it because of your username). I love it, but the Raptor is tough to maneuver on the tighter trails here in PA. I will most likely sell my Raptor and buy a new Tacoma when the next generation is released, hopefully around this time next year.
