Be careful about leaving your RV plugged in all the time. Some units you can---- some you can't. We once got a new RV and in a short while burned up the batteries.. We had always left ours plugged in 24/7. A leading cause of battery failure is overcharging. If your converter doesn't have a 3 state charger the battery gets a constant charge of 13.5 volts, and when completely charged this voltage is too high for a float charge and boils off the battery water in time, and ruins the battery. When we burned up our batteries, I asked why you can stay in one plugged in all the time, but not store one like that. They said when staying in one you are constantly 'using power" too...not just building/storing it. Good lesson learned a hard and expensive way that leaving a RV plugged in all the time during storage is not always a good idea.
Do you have a batter disconnect switch on your motor home? Our trailer has none. We play it safe by not plugging our trailer in. The first of every month, we plug into electricity for 24 hours to charge the batteries..and we run the a/c for an hour. Since you have a generator, would be good to unplug from electricity and run your generator for two hours under a load--- like your a/c running. You can kill two birds with one stone and get the exercise both a/c and generator need to keep them well lubricated.
I hope your electric plug has enough power to run things other than a battery charger.... Get one of these to check it:

If it is in the green area....you can run a/c etc. You can find these AC Voltage meters for about $15, and they are good to have to check quality of electricity in the RV parks you stay in. A/C would come in handy for cleaning your motorhome on those hot days. Also when you are going on a trip....we always turn on our refrigerator 24 hours in advance and run on electricity to pre-cool it. Good too to be able to vacuum and all the other cleaning things one needs electricity for. Check it out, perhaps your plug at storage will support more.
Did you sleep last night at all....or were you too wound up? Grin..
Happy RV dreaming!!
