I just got here to this site. I had to reply to this as I worked at Nissan dealer until last year and now work at a Cat and Mitsubishi dealer.

I was at the Nissan factory two years ago when they started collaborating with Cat and Mitsubishi. The engine is Nissan and the transmission is Mitsubishi. The "drive train" is the same in both and I recently saw a new brand (to me) called Tusk that had the same combination.

Having worked with both, I have seen many differences. They are different forklifts with the same propulsion system.
