Forest River is recalling 175 2016-2017 Flagstaff and Work And Play recreational trailers because the MB Sturgis LP regulator can leak propane into the indicator sight glass and cause it to crack. A cracked sight glass can release propane near an ignition source and raise the risk of fire. The Forest River dealer repair will be free once available.

What's wrong?
The liquid propane regulator on the 2016-2017 Forest River Flagstaff and Work And Play trailers controls gas flow from the propane cylinder to appliances such as the stove, furnace, or water heater. It reduces cylinder pressure to a usable level before propane moves through the trailer's LPG lines and fittings. That control depends on the regulator diaphragm and plastic sight glass staying sealed.
On affected trailers, the MB Sturgis regulator has an imperfect crimp. Gas or foreign material can seep around the diaphragm and reach the cavity under the plastic indicator window. That material breaks down the plastic over time, and stress cracks form in the sight glass. Once the sight glass cracks, the regulator has a path for propane to leak.
Owners can look at the plastic indicator window on the regulator. Cracking, clouding, or visible deterioration is the warning sign before failure.
Who's affected?
Covers both Flagstaff and Work And Play trailers across the 2016 and 2017 model years, all tied to LPG system lines and fittings.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
A cracked indicator sight glass can let propane gas leak out. With an ignition source nearby, that leak increases the risk of fire. Cracking or deterioration in the plastic indicator window is a warning sign, so treat visible damage as a reason to stop using the propane system and arrange service. Repair will be free at any franchised Forest River dealer once available.
What should I do?
- Check your VIN to confirm your 2016-2017 Forest River Flagstaff or Work And Play trailer is included in this recall.
- Watch for Forest River's owner notice, mailed August 1, 2016, because the final repair plan was still being developed.
- Call Forest River customer service at 1-888-291-6665 and reference recall number 16V450 to ask for the current repair plan.
- Avoid using the LP system until Forest River confirms the repair path for the MB Sturgis propane regulator sight-glass leak.
- Keep ignition sources away from the trailer's propane regulator area until the repair is complete.
What happens at the repair
Forest River had not determined the final repair plan in the recall remedy record. Once the repair is available, a Forest River technician will complete the propane regulator remedy at no charge under the recall. The affected part is the MB Sturgis liquid propane regulator, where propane can enter the regulator sight glass and damage it. Forest River has a general reimbursement plan on file, so documented out of pocket repairs tied to this LP regulator issue can be submitted through Forest River customer service. Keep repair orders and payment records with your recall paperwork.

Frequently asked questions
What is recall 16V450?
Recall 16V450 covers 175 2016-2017 Forest River Flagstaff and Work And Play recreational trailers with an MB Sturgis LP regulator defect. Propane can leak into the regulator sight glass, degrade it, and crack it. Forest River has not listed a final remedy plan.
What should I do if my 2016-2017 Forest River Flagstaff or Work And Play is on this recall?
Check your VIN to confirm your specific trailer is included in recall 16V450. If it is, contact a franchised Forest River dealer or Forest River customer service at 1-888-291-6665 and reference recall number 51-05312016-0205. The final recall repair is free once Forest River opens it.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the recalled defect at no cost. Forest River had not determined the final remedy plan in the source filing, so ask the dealer what repair guidance is open for recall 16V450 before bringing in the trailer.
What is the safety risk in recall 16V450?
The safety risk is propane leakage and fire. If the regulator sight glass cracks, propane gas can escape from the LP system. In the presence of an ignition source, that creates a fire risk. Keep the LP system shut off and ask the dealer for handling instructions.
What if I bought this Forest River trailer used?
The free recall repair still applies to a used trailer. Recalls follow the VIN, not the first owner. Check your VIN, then give the dealer recall number 16V450 and Forest River recall number 51-05312016-0205 when you ask about the repair path.
