Shockingly, no! I think it's only on third-party sites, though. Edit - Wrong fire truck. That one seems to be automation, but this one isn't.
it's a fictional fire truck mod made by @MaxieTheFoxxie. it's available at his discord server: https://discord.com/channels/941119473161744394/1061740208393044158 it's not a third party or a automation mod
That's not the one that was in the image. The image one is different (as I said in my post edit). The screenshot one is probably automation.
MTL Sherman was a reupload of this mod from some random user on ModLand. That is not the official one. Only place I have officially posted this is on my MediaFire account with a download link in my Discord Server. --- Post updated --- Correct. It is the GTA 5 fire truck with the light setup of the GTA 4 fire truck.
Dang, I was looking for that truck last year (the first one). It appears, from my searching, that it is a private mod and is not released to the public. BeamNG Fun used it in a video and it has good crash physics. It is not on automation or the BeamNG website. Mods like this are private and only released to content creators, such as Camodo and Neil's custom Sunburst skins (created by @Shadows).
