I am definitely seeing a large number of the Crewmax versions (at least for the ones I am up close to). They are easy to spot becasue they have "real" door handles on the rear doors. Probably some of the ones I see passing on the highway are double cabs and I just didn't realize it. I just don't remember seeing a single regualr cab, but I just looked at the local dealer inventory, and they do have at lease one regular cab, regular box model in stock, so they do exist. I was a little shocked at the price - with minimal options, the 4x4 version was over $30K (before the $2K rebate). On the other hand, a similar Tacoma was only $2K less. I guess the Frontier will have to last another couple of years.
