2018 Keystone Alpine Electrical problems

The power wire to the emergency breakaway switch of a 2018 keystone alpine 3400rs 5th wheel trailer was wired directly to battery power without a fuse or circuit breaker to protect it. Due to another manufacturing problem, that power wire was pinched between the pin box (5th wheel hitch) and the fiberglass front cap of the trailer. The insulation on the wire chafed during travel due to flexing and eventually shorted to the pin box which is chassis ground. As the wire was not fused, it got very hot, melted the insulation on the wire, and melted to other wires in the loom. There was a high potential for a vehicle fire. *Tt *tr *tr
