Hi and welcome to mightyram. Your truck looks like it's a D50 Sport. It has the colour scheme and the wheels. If those are genuine miles, that truck has hardly done any work in nearly 40 years! These trucks will outlast the apocalypse if they're serviced and checked regularly (and rust hasn't found it's way through everything) It looks like you've found the recommended maintenance thread - this is a really helpful thread for new-to-Mitsubishi truck owners.
