I'm looking for a truck with 2-range transfer case that has a center differential, that is lockable. I'm having a hard time figuring out which manufacturers had this feature (If any). I've found it really hard to find this information in general for everything but the Hijet. [There is a very useful thread about the Hijet here: https://minitrucktalk.com/threads/awd-of-hijet-models-history.22756] The Hijet had a lockable center differential option, but only in a single range version from 1986-1997. I'm really targeting the 1990's with my budget, but if figured I'd ask universally in case it is useful for someone in the future. Thank you, Chris
