Hold your horses.

Toyota is planning a Diesel Tundra soon.

Skip the Powerstroke. It's Crap. On a well-built solid frame truck. I have an '06 and it's already been in for warranty work for oil leaks. But then again, it's carried my family and our camper across the US and back in 120º heat, and the only things that have gone wrong in the 4 years I've owned it are 2 tail light bulbs burning out.

Skip the Duramax. It's a decent engine, but comes wrapped in a GM product. I've owned a Chevy and will never go through that again. They should change their slogan to: "The Only Vehicle That Will Break Down While Parked and Turned Off."

Cummins? Good, but how much longer is Dodge going to hang on?

Other than my input, pretty good advice all-around.
