I’m thinking of adding a 2000 watt converter to my 2014 Rushmore 5th wheel to use during lunch stop for microwave, or TV, or a fan. (I know AC isn’t going to work). I have two Battle Born batteries. I don’t want to do a lot of internal wiring.
What are thoughts of extension cord from inverter to 20amp shore power connection for limited microwave, or fan, or TV use?
Battery charger would have to be turned off.
Is this a crazy idea? Let me know what you think

You will need to mount the inverter (not converter, that is what is used to transform 120V to 12V/14.4V) near the battery setup and have large cables as short as possible. You'll need to wire in a large female 14-50 RV plug. You'll then need to see if your large 50A RV cable will reach there. It'll be a PITA to pull out the heavy cord and fiddle around all the time to be honest.

There's a reason I spent the better part of a weekend rewiring th underbelly and 120V breaker box. I just press a button on my remote and voilà, 120V everywhere in every outlet.

Just remember to turn the charger off (and on again when you are done). Other than that it seems to be an easy thing to do.

You can use a 12 gauge extension cord from inverter to shore power inlet with an adaptor to the 30 or 50 amp receptacle.

Check your microwave watt draw, not cooking watts. 2000 watt inverter should do it but with nothing else.

I would suggest the Multi plus II 3000 watt inverter because it can do so much more if you ever decided to add more to the system . All you would need is a Digital multi controler ( $140 ) with a cat 5e to the DMC to the inverter. Then you would run the coach power cable to the inverter and reconnect the original coach power to the inverter . You could use just your two battery knowing you can NOT run the AC unit (you need about 140 amps at 12 volt to power AC off the inverter) . Every outlet would be live all the time in the coach , you could use the 15 amp park power and current limit the utility side if you had limited power . I have one , nice very flexable system forward compatable product line. I would strongly suggest you install a Victron BVM-712 battery monitor as part of the DC system .
