As far as I can tell, they're not taking tight trails all the way up to the Arctic circle, they're taking well traveled roads. I realize that Tundras are much larger and are not made for driving Jeep trails and rock crawling. I asked the question because based on the Alaska Expedition, IMO, the Tundra would've been a more suitable platform. I've never owned a Tacoma but contemplated buying one over the Tundra because of their reputation. But in the end, it came down to the Tundra because I wanted a truck that could haul and tow without breaking a sweat. Previously, I owned a 4th gen 4Runner with the 4.7 V8 so I knew that I wouldn't be satisfied with a V6 after driving the 4.7. IMO, the 4.7 is one of the best motors that Toyota has ever built. I hope the 5.7 is every bit as good.
