2006 Ford F-350 Super Duty Crew Cab “Fummins.” Yes, that’s spelled correctly—a Ford with a Cummins—and this is far from a typical build. We confidently put this truck up against any out there as one of the most thorough and detailed Cummins conversions available, built on one of the most rust-free and exceptionally clean platforms you’ll find. That’s a bold statement, but if you watch the video, you’ll understand.

This vehicle was completely disassembled, starting with a powder-coated frame. It underwent a full color change on a rust-free West Coast truck that was specifically sourced for this project. It is a Lariat with a perfect interior and a manual six-speed transmission. Power comes from a compound turbo 5.9L 12-valve Cummins, with all required modifications—and then some. This truck not only makes incredible power, but delivers it smoothly, with a driving feel comparable to a gas engine.

The bed is brand new with a spray-in liner and has never been used, topped with a custom-fitted hard tonneau cover. Even the cruise control functions properly—every feature was integrated to operate just as Ford originally intended. A SuperHitch 20K hitch has been installed, and stainless hardware was used wherever possible.

A truck this clean could command our asking price even without the conversion, but with parts and labor combined, over $80,000 has been invested into this properly executed build. Please watch the video with the previous owner—you can clearly see the level of detail and effort put into this truck from top to bottom. Full frame-off builds like this are extremely rare, especially at a fraction of what it would cost to replicate
