Any comments on advantages or disadvantages over one or the other?

The "Converter"/ Charger changes AC to DC The "Converter" provides a stable source of DC to power Lights, Radio, ... in a trailer, and of course the Charger charges the battery. Modern chargers will provide both functions. The Inverter/ Chargers as you know works both directions provides battery charging when power is provided by shore power, and will provide AC when the trailer is on battery power. To answer your question if you find a need for AC power when you're Boon-docking the Inverter/Charger will work fine. Of course you will have to be very careful to tend your power usage while using the Inverter because they are "power suckers". I personally find no need for AC power when boon docking so I chose not to install one. The second reason for not having one is cost, I prefer to spend my dollar on the best charger I can afford.
If you look at the power requirements for appliances you would have in your trailer you will find that it would take a substantial inverter to run them 2000W or better.
That would mean you would draw 2000W/12.5VDC= 160amps that is a very large draw on your battery. This means you also have substantial expense for cable and that needs to be sized correctly. This can all be done but you need to ask the question, do you really need it?
