I'd probably get the Tundra. However, if I could have anything, it would be a Tacoma with the TRD offroad package. I spent all weekend driving my friend's 2500 Chevy around town and it's cool and all, but gas mileage sucks and they are annoying to drive. It was super fun driving it offroad, because it's so burly, but it really does drive like a tank. It handles like shit, turns like shit, and in general is only fun offroad. Therefore, the smaller Tacoma would be a little more sporty, handle better, and be even more fun offroad.
