I see your unit is a 2015 so I can guarantee it has them.

Well, not unless they are inside the trailer. I previously followed the red lead from the battery to the point it enters the trailer. No fuse of any type. I do have a recent theory though. I have a wireless brake controller. Powered from the tongue battery. Perhaps when that was installed this they omitted the fuse. Any way there is definitely no fuse in the red battery lead outside of the trailer.
