Thank you everyone for the replies and happy holidays!
My husband and I plan on living in the camper full time and travel for at least a year.
We dont plan on being plugged into shore power hardly ever, so I'm looking for something "off grid."
I talked to a friend yesterday who dabbles in electric and he pointed out one huge mistake he thinks I made. I plan on running everything through an inverter. So he said I wouldnt need to multiply the amps by 12v because I'm running everything off AC via the inverter. So, the amps would not increase, does this sound right?
Thanks for pointing out that the chargers and etc list the maximum volts & amps, that's a good point.
I have also recently stumbled upon people using 6v batteries which increases amp hours quite a bit. I've seen for example say they have six 6v batteries, they'll wire pairs in series to create 12v then run them in parallel to up the amp hours. They sell relatively small 6v batts that start at 225ah.
After learning all this, things seem much more possibly without having to use a huge bank and or huge array.
When I finish my new list of appliances/watts/wh etc - I'll share it here to see if it makes sense and for future folks with the same question.
