Welcome! This is my first *real* mod for BeamNG, I've wanted to create it for a long time. This mod adds two new frames (double cab and single cab) to the D series, which have an additional slot for the third axle, with the regular axle pushed forward to make room. The frame also allows you to add additional accessories to it, increasing its versatility. I made the most of the details of the stock BeamNG to reduce the file size and make the mod "simple".

It is still under development, so some configurations of parts may break beams/behave strangely, but overall I think it is strong enough to be considered a release.

This mod should go well with almost any other mods, but keep in mind that non-standard wheels/tires will not be available on the third axle. Also, the third axle is a bit more limited in which wheels can be added at the moment (6 protrusions, HD 8 protrusions), but more are planned to be added in the future.
