whats your favorite diesel pickup

Not anymore. Cat left the on-road engine market after 2007. The Freightliner I drive has one of their last on-road engines (a 250HP C7).

Umm... not anymore? There's still plenty of Cats around.

That's like saying that because no new slants are being built you can't have one "anymore."

And the question I responded to was, "are there any other diesels than Cummins?" Didn't say anything about "on-road."
