What's wrong?
The propane compartment on a 2019 Keystone Cougar fifth-wheel trailer is the enclosed area that holds the LP propane supply separate from the living space. That separation matters because propane belongs outside the cabin area, while appliances receive fuel through the trailer's controlled propane lines and fittings. Sealed seams around the compartment help keep leaked gas from moving into areas where people sleep or sit.
On affected Cougar fifth wheels, the compartment was not sealed correctly along the bedroom floor and the pass-through compartment during a design change. Those gaps create a path from the propane storage area toward the living quarters. If a propane leak occurs inside the compartment, gas can travel through those openings instead of staying contained outside the occupied space.
The warning sign is the trailer's interior safety alarm. The safety alarms inside the fifth wheel are designed to alert occupants when propane gas enters the living area.

Not every 2019 Keystone Cougar trailer is on the list. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
A propane leak into the living area can increase the risk of injury or fire. If propane gas enters the living area, the safety alarms inside the Cougar will alert occupants. Treat any alarm as a reason to leave the trailer and contact the dealer before using propane again. Repair is free at any franchised Keystone dealer.
What should I do?
- Check your VIN to confirm your 2019 Keystone Cougar is included in this recall.
- Contact a franchised Keystone dealer to schedule the free propane-compartment sealing repair that helps keep propane gas out of the living quarters.
- Bring the recall notice if Keystone sent one. If not, reference recall number 18V320 and Keystone recall 18-321 when you call.
- Avoid using propane appliances until the dealer seals the LP compartment.
- Keep receipts for any related out-of-pocket repair and ask Keystone customer service about reimbursement.
What happens at the repair
At the dealer, a Keystone technician seals the inside of the LP compartment along the floor line and side wall. That sealing work is meant to keep propane from entering the living area if a leak develops in the compartment. The recall repair is available now, and parts and labor are free under the recall. Tell the service desk this is Keystone recall 18-321 if they need the internal recall number.
