I "think" in the battery compartment of the fifth wheel there is a 30 amp fuse between the battery and the remainder of the electrical system. Would it be OK to incorporate that fuse into the starter wire circuit, or would the load be too close to the limits of the fuse and blow it, especially if other loads are energized in the trailer?
Alternatively, I could run the starter cable directly from the battery to the genset and put another ? 30 amp? fuse in-line near the battery?

It should be fine to use it as an over current protection device as long as you are not running all the other 12 VDC accessories in the camper with the converter off at the same time. It would also need to be a slow-blow or time delay type fuse/breaker. The locked rotor current of the starter is high enough to quickly blow a conventional fast-blow fuse when you hit the start button. Personally, I would replace the one shot fuses from the battery to the camper with same size automatic resting circuit breakers like the ones used on your vehicle headlights, backed up by a fuse or fuseable link that is rated about 10 amps higher.

If you do this, you could even tap the 12 VDC wire from the converter to the battery and perhaps save some wire to the generator. No need to run a negative wire, just use the RV frame as the neutral. One caution: If your generator has a neutral to frame (ground) bond REMOVE IT before connecting to the RV battery negative post or conductor. You do not want the RV frame to become a "hot" part of an AC circuit without the benefit of a proper grounding connection.

The additional fuse or CB for the starter would be OK too.
