Take a look at the Nissan Titans as well. Great power, lots of room, look good, and are another Japanese vehicle (read as likely to last longer). The old man bought a new one in '05 and it has been a great vehicle. Earlier this month he raced my uncle's '07 F-150 going down I-90 and flat out spanked him.
Or better yet- wait a few years until Nissan and Toyota release the full-size diesel-powered versions of their trucks. Talk about long lasting vehicles with power to spare! Seems like it would be worth the wait to me.
