## The problem

Heartland Recreational Vehicles, LLC. (Heartland) is recalling certain 2018-2021 Mallard, Shadow Cruiser, Sundance XLTTT, Wilderness, Prowler, Trail Runner, 2018-2019 Pioneer, Terry Classic, 2020-2021 Lithium, and 2021 North Trail trailers equipped with a Winntec model 6020 two-stage propane regulator.  The regulator may fail, causing an increase in propane pressure.

## The safety risk

Increased propane pressure can enlarge the flames in gas appliances, increasing the risk of a fire.

## The remedy

Dealers will replace the regulator and test the propane system for leaks, free of charge.  Owner notification letters were mailed August 3, 2021.  Owners may contact Heartland customer service at 1-877-262-8032.
