Cat did build a lift. Originally, Towmotor. Later changed to the full Cat name. Early truck such as the old M40 series were updated (heavily) Tomotors. Later Cat built the truck that would eventually become the Daewoo. Cat had at some point and time, contracted Daewoo to build the Cat trucks for North America (we US at least) Later after the Cat / Misti deal Daewoo ended up selling the Relabeled Cat truck.

Thats a pretty rough history, I may be off a few details.

Mitsi stopped using a 3.0 v in ther larger trucks (6000lb capacity and higher some years ago in favor of the GM 4.3 Vortec v6. ( I think it was cost and reliability issues.) The 3.0 Mitsi engine was the same engine used in Chrysler/Dodge/Plymouth minvans and some cars. Although the engine was tuned and built for industrial applications. other reasons for the 3.0-4.3 change may have been brand recognition, how many people have a 4.3 in their SUV or pickup?

As far as the change to the Nissan engine, I cannot elaborate. Havent worked for a Mistsi dealer in a number of years. But I can say, that in my experience, MCFA of Houston, doent make a change unless is positively affects the bottom line.

Heard the Possible Cat Mitsi issues from a Cat dealer employee. Take it for what its worth. His statement was Cat was unhappy.
