can't read the writing on the circuit breakers.  do any of them pop when trying the ac?    

   if you have an auto switch, you do nothing after starting the gen.  i don;t have auto switch so i have to plug the shore power cable into the gen outlet to use the gen. 

 makes it either or     shore power or gen

anything that needs 120v ac power needs the power from the pole or a generator.    the converter  (120v ac to 12v dc) uses some energy to do its job, hence the heat.

 all the 12v stuff always runs off the "boat battery", the converter keeps it charged.'

  as said, the fridge runs on propane---no electricity needed.    the furnace uses 12v from your battery to run the fan

I posted pictures in this strand. 

So from what I understand I should be able to run the AC while I am plugged in. But I'm currently plugged in and I cannot run the AC without everything else in the vehicle shutting off. Is it just too much of a draw? Do I need to be plugged in to a different place? And another question I tried turning on the generator thinking that would give more energy to the system. But when I run the generator nothing different happens. Is there some switch I have to flip to make the power come from the generator? Thank you for all these explanations. I feel clueless.
