NHTSA Campaign Number: 22V336

Manufacturer Kuntry Kustom RV, LLC

Components EQUIPMENT

Potential Number of Units Affected 172

 

Summary

Kuntry Kustom RV, LLC (Kuntry) is recalling certain 2017-2020 Rich Specialty Trailers Sanitation, Movie, Office, and Bunk House trailers, equipped with Winntec model 6020 two-stage propane regulators. The regulators may fail, causing an increase in propane pressure.

 

Remedy

Dealers will replace the regulator, free of charge. Owner notification letters were mailed June 7, 2022. Owners may contact Kuntry customer service at 1-260-593-2208.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

 


Certain Winntec model 6020 two-stage propane regulators installed on these vehicles may supply elevated, intermittent or low propane pressure to the appliances due to a second stage valve seat that can fail to regulate propane flow and pressure. An increase in propane pressure, could cause the flame of the appliance to become larger, and under certain rare circumstances, may ignite adjacent materials resulting in a fire.

Appliances that can be affected by an excessive flame are the LP gas stovetop, LP gas oven, LP gas hot water heater, LP gas furnace and LP gas refrigerator. An increase in propane pressure would also cause the regulator to vent propane continuously through the pressure relief valve. In an enclosed area or under certain conditions, the vented propane could accumulate at the front of the specialty trailer and if ignited could result in a fire or explosion.

Remedy consists of removing and replacing the propane regulator with a new regulator and performing standardized LP System Checks. The repair should take less than an hour to perform and this will be done at no labor or parts cost to the customer. Please see attached inspection and replacement procedures.
