It's OK for the converter negative output to be connected to the frame (chassis ground), or for it to be connected to the negative battery terminal which, of course, is also connected to chassis ground. If the battery is a long distance away, a nearby solid chassis ground saves on wire and may well be a lower impedance current path. My converter is wired with the negative output going to chassis ground, in fact.
The converter's chassis bonding lug must be connected directly to a chassis ground. This is a safety connection, not a current carrying connection. The instruction manual for the converter covers this pretty clearly. (This is needed to carry ground return current in the event of a converter or wiring fault, rather than having the full 60A converter output going through the AC input ground wire which is in no way sized to handle that current.)
