Congrats! I can certainly see how the extended cab provides much more room. You may discover that you like the extra room so much that you wish you bought the quad cab (or whatever they call it.)

We've got the 03 Extended cab, and it's great for two people(and their dog.)But sometimes,it would be really nice to take along two more adults on one's offroad ventures. Of course, then the bed gets pretty short. It's a tradeoff.

Of course, the quad Taco is now available with the long bed. But then the wheelbase becomes so long that it hardly feels like a mid size, let alone a compact, truck. Nevertheless, I think that is what we're eventually going to get.
