Back to the original topic, and bearing in mind that this is the European Forum.
Different marketing names are used in different countries/markets, which do not always correspond to the two "divisions" described here. Examples are 70 series called Prado, 90 series Prado, 120 series Prado; or as it is around here, where the early 90's where marketed as LC Prado, while later years where just "Land Cruiser". The 100 was then re-branded LC100. (I find it silly to call the medium duty LC "LC", while the "full" heavy duty gets a deviating name). Around here it is still the same name (LC) for the small version, while the 200 is the LC-V8.
The 90s, or Prados, are normally (or often) equipped with RDL, although they are not called Colorado.
Suggesting to either make a comprehensive list of the different models, series, and marketing names;
or just stick to the different series and/or model codes. That would make it easier to communicate/discuss across borders and continents.
A list would reveal the Australian, European, UK, Japanese marketing names; and specialities like the LC400.
