What's wrong?
The wastewater holding tank vent pipe in the 2026 Forest River Flagstaff and Rockwood recreational trailers is part of the plumbing system for the black water tank. Its job is to route gas from the waste tank up through the roof and out through a vent cap, so odors stay outside the living space.
On affected trailers, that black vent pipe was not installed all the way through the roof. Because the pipe ends inside the trailer instead of outside it, sewer gas has a path into the vehicle. Forest River traced the issue to a manufacturing error, and the corrected setup installs the vent pipe through the roof with a cap for proper ventilation.
The warning sign is a sewer gas smell inside the trailer. If you notice that odor, treat it as the sign that the plumbing vent is not carrying waste tank gas outside the vehicle.
Who's affected?
Both trailer lines involve the same plumbing pipe/fittings component.

What's the safety risk?
Sewer gas inside the vehicle increases the risk of injury. A sewer gas smell is the warning sign operators are told to watch for. If you notice that odor, stop using the vehicle until a dealer installs the vent cap. Repair is free at any franchised Forest River dealer.

What happens at the repair
At the dealer, a Forest River technician installs a vent cap so the waste water holding tank ventilation pipe terminates outside the trailer. The recall repair is free, with parts and labor covered. Forest River says the affected trailers were still in dealer inventory, so owner letters will not be mailed. If you have already paid for a related vent cap or holding tank ventilation repair, contact Forest River customer service and keep your repair documentation for the manufacturer's general reimbursement plan.
