Is there a way that an RCD, or similar device, can be incorporated to

Should both the neutral and earth be wired to the chassis of the vehicle.

If you ground the Neutral *before* you take it to an RCD, it should work.

There has been much useful advice already given but it is worth saying
that "some" generators deliver from a centre tapped output winding.
Make certain yours is not one of them.

If it is, grounding one leg will simply pop the breaker each time it
starts. If this happens, whichever leg you ground, then you'll know.

NT

If he has a generator with a centre tap connection to earth and he
then earths one output before his protective device the net result is
a short circuit of half of the output winding. Running the generator
engine will risk burning out that half winding. (Assuming the
generator will excite with a short circuit output - some do some don't)
