IIRC, you have a single group 24 battery up front on the tongue. Problem is that when you add another battery, have potential charging challenges because both batteries are not of the same age and charge retention rate. This leads to uneven charging.
Basically, you need to either get a larger external box fabricated, or go with a sealed, vented box for the inside of the trailer as close to the existing battery as possible. You then connect them in parallel, or (+) to (+) and (-) to (-) with at least '0' AWG cables.
I would also change out your converter to a modern 3-stage unit that will keep your batteries much happier than with the stock converter.
While you're at it, why not look into AGM batteries. They do not out-gas like liquid cell batteries (the kind you have to fill) and last longer with better draw-down characteristics. Plus, they re-charge faster due to their lower internal resistance.
Now that I've probably thoroughly confused you.......try the search function for several of the many posts on selecting the proper batteries for your trailer.
If you can't find answers....just ask away!
