If what you want is a reliable tow machine get a 2500 HD parts truck with a 6.0L LQ4. 300 hp at 4400 RPM and 360 ft-lb at 4000 RPM and it comes with a 4L80E that'll fit under the transmission tunnel. My 2005 tows just fine. Yes it only gets 13mpg and 11 towing. That's noticeably better MPG, HP, and torque than a carbureted or TBI 454 and I'd have to run an awful lot of tanks of fuel through at 18mpg to pay for a dirtymax.

Diesels are trendy so the prices are outrageous.
Cummins engines cost a pretty penny.
The 6.2 & 6.5L Detroit AMG Diesel engines are a minimum of 20 years old now. The dirtymax is newer but any half decent dirtymax truck is going to be more coin than a decently running LQ4 equipped 2500HD.
