    I hope so, since that's exactly what I'm in the process of doing with Coho.
    All our ac is produced by a 3kw inverter - including the refrigeration. We
    have seperate alternators on the Cummins NHN, one for the house & one for
    starting bank.

    I bought a used Westerbeke 4kw genset, and after repairing it I'm mounting
    a 200A 24v alternator (from ebay) to run off the crankshaft auxiliary
    pulley. There's some fiddley welding and grinding involved in the mounting
    for the big alternator, but the idea is pretty simple. Maybe Arild will
    chime in - he's been arguing for this kind of setup for some time. We have
    8 GC's in 24v configuration. the a-c side of the genset just goes along for
    the ride, and as a backup.
