Is this unit sufficient enough to run the camper 12v system, or go with a 60 amp?
A 45 amp converter/charger should be sufficient, unless you are upgrading to one of the variable-capacity water pumps, which draw around 20a all by themselves. If you do end up adding a second battery, then a larger converter would provide somewhat shorter charging times, which sometimes matters to people who try to charge batteries by running a generator an hour at a time.

Most if not all camping will be where hookups are available, or have a generator if necessary. Also, do people have more than one battery in there AS, and would the bennefit be longer 12v while not plugged in?
Adding batteries is a common mod, and the larger trailers now come from the factory with two. The benefit is, as you say, longer 12v operation without being plugged in, particularly when running the furnace.

You can run a larger converter as long as the wiring between the converter and the batteries is large enough to handle the current without overheating. For a 60 amp converter you would want 6 gauge wire or larger for the entire run.

I'm wondering the same thing. My trailer came with a 50-amp converter. How high in amps can I go when buying a new converter without having to upgrade a lot of wiring, etc.? I don't want to go nuts here with overkill. I'm just wondering. Since I'm getting a new converter, are more amps better? If so, how high amperage is reasonable for my trailer? Right now the main battery cables are #6. The white and the red cables that actually hook to the converter are #8.
The #8 wiring is marginal for 50 amps and will tend to overheat at the terminals unless the terminals are of unusually high quality. If you replaced it with #6 you'd be good to 60 amps.

More than needed is ok as long as the wiring is large enough to handle it. Even with only one battery the battery will easily take 30a while charging and if you have all the lights on and the furnace running you can hit another 30a.

The power for the breakaway switch comes from the "house" battery.
Yes this is how I hooked up my power jack on our '66. But be certain you include an inline fuse.
