In July 1965 the T430 Miler was replaced by the T440 series. This truck featured a double wishbone independent front suspension and a 5 speed gearbox, making it significantly more advance than it's direct rivals the Toyota Stout and Nissan Junior. The T440 had the 1500 engine and the T441 had the 1900 engine.

Following the Prince merger with Nissan, for 1967 onwards they would be sold under the Nissan name. Also at that time the Miler started to instead use Nissan engines instead of Prince engine with the T446 Nissan Prince Light Miler using the 1595cc Nissan R engine and the T447 Nissan Prince Miler was fitted with the 1982cc Nissan H20 engine.

This series stayed in production until October 1970 when it was replaced with the 140 series Nissan Miler, which was simply a rebadged version of the 140 Nissan Junior.

My research is currently incomplete with regards to the Miler range after 1965, and what is shown below is not a complete list of variants. There are a few models I am aware of such as a double cab and a lighter carrying capacity model, but at this stage I am not confident that I have the correct model codes to assign to these vehicles. This page will be updated when I complete my research.
