Inverter question

Ok let me better explain this. We got along fine without an inverter until we got the e-bikes. I bought an 1100 w inverter to charge the e-bikes and simply planned to run an extension cord from the inverter which is near the house batteries which in this motorhome are under the hood. What I wound up doing was running the extension cord under the chassis in a split loom to the back of the RV where the bikes are on their rack I connect the chargers which are in a mesh bag securely hanging off the seat post on one of the bikes and then connect the magnetic charge plugs to the bikes. This way I can charge the bikes while I'm driving. Otherwise the big batteries in these bikes are a bit much for the two house batteries and will deplete them quite a bit for a full charge. Now since I have the extension cord outlet at the back of the RV it's very close to the shore power cable and easy to plug in simply to run the coffee machine. I've been dripping coffee by hand which is okay but it would be more convenient to just have the machine make the coffee. So I would shut off all the breakers but the kitchen galley where the coffee machine is plugged in. No big deal and not worth it for me to be wiring the inverter directly into the breaker box. I understand this is a bit too "Jerry rigged" for some of you but it's cheap and functional so I'm good with it.
