Depends on the inverter, the higher end ones $$$$ are pretty efficient but the smaller store bought ones are wasteful. But I am working toward a 12v system myself, for one thing that means all my equipment can work easily from a vehilce in between home and the cabin. The other thing is the inverter is an extra piece, point of failure, etc.
I'm running automotive (cigarette) plugs in parallel with Anderson power poles and some 12v power cords I'm converting to them.
I'm also using automotive wiring, fuse blocks, etc, same small metripack as my vehicles so I can have fewer types of spares (allow for stocking more) and borrow parts from vehicle for cabin or vice versa.
