Gypsy, hope you have fun on your future job. Sounds like a beautiful location.
I can only tell you about my experience with a generator in a Class B.
When I drive, my one house battery gets charged. At night when I stop at a Wal-Mart I turn on my inverter (1000W - $100 I think) and plug the TV and/or DVD player into the 12Volt socket and the inverter. I can watch TV for several hours and my lights work fine too, all running off the battery.
When it has been cold, I turn the furnace on (propane) and it (fan) runs off the house battery as well. I have never run out of battery power for those late night stops.
If I want to run my microwave or air conditioner, I push the generator button and start it up (propane). I also turn the generator on when I want to plug in the blow dryer.
I have an on and off switch for my house battery. I keep it shut off all the time until I need to use it.
I have never tried using a crock pot off the battery/inverter. It might work, but your battery may not last that long. Is there possibly an electric plug available somewhere close by - bath house, storage building, etc.? Maybe you could carry the crock pot to the electric plug?
Trust me, this stuff isn't difficult. It just takes practice to figure out how it all works and then it is easy.
Regarding your generator, yes, you definitely need to check it out because the worst thing you can do for a generator is not use it. It is good to run it under a load (air conditioner) at least once a month for at least 20 minutes. When I bought my Class B the previous owner said she rarely used the generator. DH checked it (oil, added propane) and I've never had a problem with it.
Oh, that's a lie, I did have a problem with the generator last year. It kept shutting off for no apparent reason and the repair shop couldn't figure it out. Finally DH figured it out - my 5 lb. Chihuahua was bumping into the on/off button when I wasn't around and was shutting it down. We fixed the button where it won't switch off when she bumps into it - problem solved.
Have fun learning about all your RV systems - once you learn you will wonder what all the mystery was about.
