Off and on I see posts regarding changing out the 12 volt battery to two 6 volt ones.
In the past thirty years I have had three trailers and never had a problem with the single 12 volt battery so could someone please explain the reason for swapping to two 6 volt ones.

2x 6v is a solution to some issues. If you are good as is then just carry on. You will know when you need something different. Although soon it will be lithium batteries over the GC2 when a better system is needed.
Don't fix what is not broken.
