Using Multi-Dae to add Another Cab to the H-Series

Been trying to get another cab in-game using multi-dae. But I can't seem to get it to work. I've been using Dummiesmans tutorial on it for other things and they've worked fine but trying to add another cab option to the H-Series has got me confused.

I've started by making a folder in my mods called "van" and putting the .dae called "van_doublecab" in it. Also adding the "van_cab.jbeam" from the H-Series in there too and renaming it "van_doublecab.jbeam". Within that I've changed the first line from "van_cab" to "van_doublecab". Which seems to not do the trick. The model in the .dae is also called the same.

If anyone could help me out with this that'd be greatly appreciated.

 

model needs a new name and flexbody section of the jbeam updating accordingly
