The defect
Heartland Recreational Vehicles, LLC (Heartland) is recalling certain 2021 Mallard travel trailers. The liquid propane (LP) hose and connector may contact the suspension shackle.
The risk
Contact with the shackle can cause premature failure of the LP hose, increasing the risk of a fire in the presence of an ignition source.
