You sure jumped in with both feet. Starting with the house power, since you have two batteries connected together if one is dead it will take out the second. Connected together you have to think of the two batteries as one. The batteries are the life blood of the house. Nothing will work if the batteries are dead. Fridge, A/C, heat (thermostats are DC), water pump, lights,,,,. You can get by using a car battery while you're getting the coach up to your standards but you will need a deep cycle battery(s) before heading out on the road. A car battery powering the house just won't last very long doing so.
Generator starting power can be either the engine or house batteries depending on how the builder wired the coach. I would guess the Coronado is wired to start off the house batteries which is why you can't get it to start.
The main and aux switches above the door are used to disconnect the house and engine batteries when you are not using the coach. Should be two maybe three big high current solenoids somewhere that the switches control but if the batteries are dead you don't have power to close the switches. Power flow is batteries - disconnect solenoids - fuse panel - loads. There could be a circuit breaker here and there but normally with DC fuses are use.
I don't know enough about your chassis to venture into it but there are many how do and will. Value is a difficult target to hit especially with older rigs. Demand will have an effect but prior owner maintenance is top of the list. What ends the useful life of a coach is water leaks, aka RV cancer. About the same as rust on a car but the problem is the damage is usually between the walls where you can't see it. If the past owners maintained it and stayed on top of keeping water out you should have a solid coach that will give you many years of adventures.
