Is there a way that an RCD, or similar device, can be incorporated to
protect any person in case they come into contact with live at any point?
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.

It will certainly be worth you getting hold of a copy of BS7671 and
reading up thoroughly on the particular requirements of section 717.
Page 206 shows a diagrammatic outline for use with a generating set
within or without the unit. Also worth reading up on Agricultural
installations in the same BS
