If you want inspiration on how to implement the cargo classes, have a look at the source of the Dutch Trainset Cargo Extension (link below). That is in NML (not sure if you're using that), but it should be clear enough on what type of vehicles I gave what allowed cargo classes, disallowed cargo classes and exceptions.
In the end it doesn't matter if a vehicle isn't refittable with the default cargos, but is refittable with e.g. FIRS.

Did this beautiful art ever make it into a working NewGRF? (other then those few trucks)
