Look at the attached photo. The breaker is the two rectangular objects attached to the positive post of the left battery, with a red wire coming out. The red wire is the power wire for the tip-out winch. I circled it.
The way it was done at the factory is not a good practice. They used two 25 amp circuit breakers connected in parallel to make 50 amps. This can lead to the whole setup tripping at a lower current than 50 amps. It is a much better practice to replace the two breakers with a single 50 amp one. I recently did this on my trailer.
