What's wrong?
The black wastewater-holding tank on 2021-2022 Forest River Puma travel trailers stores sewage from the RV plumbing system until the tank is emptied. That tank is supposed to have a ventilation pipe that runs from the tank through the roof. The pipe lets tank gases escape outside the trailer instead of backing up into the plumbing area.
On affected Puma trailers, Forest River says the vent pipe was not installed during production. Without that pipe, the black tank is not properly vented. Methane gas can build up instead of exiting above the roof, which is why the recall repair adds the proper ventilation path.
Owners can notice odors from the holding tank before the problem is found. A sewage or holding-tank smell inside or around the trailer is the warning sign tied to this defect.

What happens at the repair
At the dealer, a Forest River technician inspects the black wastewater-holding tank and properly vents it so methane gas does not build up in the tank area. The recall repair is free, with parts and labor covered. If you already paid for a repair within the scope of this defect, Forest River still wants the recall inspection or repair completed to confirm the correct parts and procedure were used. To request reimbursement, send the service invoice to Forest River's warranty manager using the address in the recall notice.
