Some things to think about...
For 110VAC
Use a breaker.
Keep the wire from the shore to the breaker box as short as possible.
I like 14-2 Romex from most applications with 15A protection. The Romex is a sheathed cable that will resist abrasive wear inside walls. If you run cable under the chassis, use flex conduit with waterproof seals.
Keep microwaves on their own circuit.
Place any inverter before the breaker panel so that you have protection when it's in operation.
For 12VDC
ALWAYS use fuse or breaker protection and protect for the smallest gauge wire that is in excess of 18 inches.
I personally recommend only using manually resettable breakers if you choose breakers. There are too many design considerations involved to make type 1 or 2 re-settables it worth the effort.
Pay attention to polarity on breakers.
Remember to consider the gauge of your return or ground wires when planning protection.
Converter/Charger outputs may require protection too.
