blowing fuse on power line to trailer
I have a 2017 Jayco Pinnacle 5th wheel pulled by a 2015 F350. The jayco is about 5 weeks old. Took a trial trip in June and noticed that the batteries were a third dis-charged after towing all day...

90% of shorted charge lead wires are inside the pigtail connecting to the truck socket socket or trailer plug. Disconnect, disassemble and look for pulled-loose strands or two connected wires touching each other.
