There has been a lot of talk about Nissan making a diesel Titan to compete with the F-250/2500 trucks. I think they should make a 1/2 ton diesel. Imagine if you could have decent towing capability and get 25-30 mpg. Chrysler is already making some Jeep SUVs diesel and I heard they plan to make the Ram 1500 available with a small diesel. I the price is reasonable they will sell like crazy (I think).
