The 2nd gen Toyota Tundra is the oldest half ton pickup currently on sale having come out for the 2007 model year. Still a solid truck although there is something not quite right about the proportions. No one seems to be sure when a new model will be released but it has to be soon. Here is a photo of the facelifted truck.
The Tacoma/Hilux is unchanged for this model year. It’s still selling well although GM made a big dent in sales with the new Colorado/Canyon.
Nissan redesigned the Titan a couple of years ago coming out with the ⅝ ton XD first. Sales were extremely slow but have picked up since the ½ ton was released. In fairness, it does look like a 5 year old Ford:
The 5L Cummins diesel in the XD is a very cool option however.
The Nissan Frontier/Navara is unchanged this year but a Mercedes Benz version called X-class came out last year. It is not on sale in North America for some reason. Anybody seen one?
