You are absolutely 100% correct. It doesn't really matter what the converter inside the trailer does. The charge controller should be an MPPT controller, and it should be set to charge to about 13.65 volts. The 200 watt panel is a little undernourished. Going to need more wattage from your panels. I suggest, if you have the real estate on your roof, buy some residential or commercial PERC72 solar panels, as many as you can fit on the roof.

Also, keep in mind that almost any battery is going to "settle", meaning that charge voltage is actually going to drop a little bit to its actual operational voltage. So, even if you charge it 14.4 volts, you're going to get a little bit of drop to the operational voltage. As long as you're well above 12.2 to 12.8 volts, you're doing pretty well. With lithium iron phosphate batteries, you're going to see more like 13 volts and above.
