I'm not going to pop the bubble to reveal everything on VEXUVIUS since you have seen whats from the outside,  As for the inside especially cockpit details i'll give you a glimps in naked 3d meshes.  The rear pretty much holds a wheel, tool boxes and stuff for truck maintenance while the front cabin mostly generic from XAVAGE meshes.  The door is thick and partially bumped hollow and open pretty much like an ordinary door.  There's a heavy duty roll cage topped beyond driver seat height for turtle protection.   Extras will be added pending what sort of variant to be produced.  The rest details will be mentioned on next episode.
