The Triton (L200) pick-up truck is the largest within the LCV range, with about two thirds of total units made. Some may call it a compact pick-up but for me it's medium sized. I'm sure it must have been a vital profit earner for the company. It started production in 1978 and the 5th generation was introduced in 2015 (pictured below).
The Delica (L300) cargo van and mini bus has also been a popular LCV, especially in the Asia and Pacific region. It commenced being made in 1968 and the first three generations were both a tradition van style as well as a pick-up version. The current model is the 5th generation which has been around since 2007. Production is holding up well considering its age.
Mitsubishi also does the Colt T120SS mini pick-up, based on a Suzuki model and made in Indonesia. It is sold only in certain Asian markets. The Minicab (L100) was a Kei sized van from 1966 forward and it was also a mini pick-up too. It seems it was again just for the Asian region. Why production dipped for 2014 is strange, but I don't know much about these Asia only models. Finally the Town Box was a high roofed Kei van produced for 12 years but now discontinued. it was made for the Japanese market.
Summary: LCV production is based around the Triton pick-up, the only model among these with any global reach. Mitsubishi is strong in Asia and that is where the emphasis has been for its LCV vehicles.
