What's wrong?
The transfer switch in a 2021 Forest River Riverstone with the optional generator prep package is the electrical handoff point between shore power and generator power. It is supposed to keep those power sources separated, so current goes only where the trailer's electrical system needs it. The power cord should not be energized from the trailer side when it is connected to shore power.
On affected Riverstone trailers, the transfer switch wiring is incorrect. When the trailer is plugged into shore power, that wiring can send voltage back through the power cord instead of keeping the cord isolated. That back feed means a cord or plug that looks ordinary can carry live voltage in the wrong place.
There is no warning sign before failure. Owners are not given a dashboard light, message, sound, or visible change that proves the transfer switch is wired incorrectly.

- Contact a franchised Forest River dealer and ask about the free generator transfer-switch wiring correction that stops voltage back feed to the power cord.

What happens at the repair
At the dealer, a Forest River technician corrects the generator transfer switch wiring so shore power does not send voltage back through the power cord. The dealer repair will be free once available. Because this filing does not list a current remedy status, confirm with the dealer that campaign 20V400 is open before you bring in the trailer. Parts and labor are covered under the recall.
