Mike,
As your coach left the assembly barn, it was set up as 30Amp 120Volt. Unless someone installed a complex and expensive power management system, you will have to use neurons to keep the AC power in line.
What you need to do is one of two things, either:
Get a look at the manufacturer's on -
Get a device called a Kill-A-Watt and measure the power consumption of -
...each and everything in the coach and then decide what you can have on line at any given time.
There are some gotchas in here.
The water heater is at the top of this list. That thing is largely autonomous and can flip on at any time when it is powered. It is best to know how to shut it down when things are close.
The converter can be, but it should not. You have a 60amp Converter/Charger? The most mine ever pulls on the line is about 7 Amps of AC, and that is not for very long.
This is called energy management. It is simple if you can use neurons, but if not then you have to plan on spending money or having the power shut down.
This is why GM elected to make all its coaches 50amp. In complete honesty, I was part of the RV world at that time and the discussion was that all RV parks would soon be either real 50amp or a thing that they called Twin-30. Fortunately, the dangers and pitfalls of the Twin-30 plan were soon seen and it has disappeared. The unfortunate thing is that this short side trip made many drop any plans of upgrade.
As we don't know what your coach came with and what has been changed in the last 40 years, you are kind of stuck doing this your self.
