What's wrong?
The external compartment outer door skin on 2017 Thor Motor Coach Outlaw, Challenger, and Miramar motorhomes is the finished exterior panel on a storage compartment door. Its job is to stay bonded to the door structure so the compartment closes cleanly and the outside panel stays attached while the motorhome is moving.
On affected motorhomes, the glue bond between the outer skin and the door structure is at risk of de-bonding. Once that bond weakens, the skin can loosen from the compartment door. If the separation continues during transit, the outer skin can detach from the motorhome instead of staying secured to the body.
Owners can see the warning sign before full detachment. The outside door skin can look or feel loose, and Thor Motor Coach says the door skin should be secured before operating the vehicle.
