What owners wrote
When attached to a trailer with solar panels, the truck will intermittently disconnect the trailer electronics which disables the trailer brakes and trailer lights. This is because the solar energy is back flowing to the truck via 7 pin connector and overloading the circuit. Having a truck disable the trailer brakes and lights intermittently is very dangerous. Earlier model years of this truck do not suffer this issue.
