Welcome to the group and some info? The trailer group is not as well supported online as the motorized but over time, lots of info gets posted that can be a big help.
If you have electrical questions, it is likely others have been there too, so help may be there?
This might be a recent post which I tagged as potential help on finding a "hidden" set of stuff that folks often overlook:
Maybe it matches what you have and you may want to file this away for later?

Enjoy and welcome to the group!
The motorized group has online drawings of lots of things like plumbing and electrical layouts that are not posted for the trailer group.
Then on that specific post, which relates to trailers, there seems to be a small button size breaker hidden in a metal box under the tongue of trailers.
that little breaker seems to be behind wires in the box and very hard to find the little reset button on the side!
If you get a nice day and time , it may be worth taking a peak from the underside to see if you can spot a metal 4X4 box as a suspect for looking for a breaker if electrical things go down on the trailer. Some seem to find it while others seem not to find?/
Possible something that was done on early year builds and then changed for later builds? I like to look ahead for the nasty little things that can trip me up right in the middle of a trip!
