I am trying to do make a subclass of a subclass of ObjectData. Is this possible?

The first subclass of ObjectData is:

  
#include "c4d.h"  
#include "c4d_symbols.h"  
  
#include "Ovehicle.h"  
  
class Vehicle : public ObjectData  
{  
...  
  
}  

The second subclass is:

  
#include "c4d.h"  
#include "c4d_symbols.h"  
  
#include "Ovehicle.h"  
  
#include "Otruck.h"  
  
class Truck : public Vehicle  
{  
...  
}  
  

But I get an error that says that Vehicle is an unknown identifier.

You are declaring the Vehicle class in the header and not the CPP file, right? The derived class must know the internals of the base class in order to include its members, process overriding members, and check for virtual methods.

Would need to see the header.
