Welcome! This is my first *real* BeamNG mod, and is something I have wanted to exist for a long time. This mod adds two new frames (crew cab and single cab) to the D-Series that have an extra slot for a third axle, with the normal axle pushed forward to allow for space. The crew frame also allows for upfits to be added to it, increasing it's versatility. I reused BeamNG assets as much as possible to reduce the filesize and keep the mod "simple".
It is still very much a work in progress, so some part configurations may break beams/act strange, but overall I think it's solid enough to be a 1.0.
This mod should play nice with pretty much any other mods, but be aware that custom wheels/tires will not be available on the third axle. Also, the third axle is a little more limited in what wheels can be added for now (6 lug, HD 8 lug), but more are planned to be added in the future.
Future plans:
- Convert the flatbed box to fit the longbed frames
- add hubs for 5 lug and normal 8 lug wheels to third axle
- extended cab longbed 6x6 frame
- Continued tweaks/improvements
Please be aware that any 6x6 that you have gotten elsewhere was stolen and never intended to be distributed, so please only download this mod from the repo and discourage others from using the now-outdated version that have circulated before now.
Now have some photos!
