What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The passenger side front window is a 2 pane window and the seal between the 2 panes has failed and the window is fogging up which makes it difficult to see the side mirror on the passenger side of the motorhome. This makes driving difficult with the fogged window.
Many of the side windows are foggy and cant see out of them especially during hot sunny days. It is hard to see through them and view the mirrors on the drivers and passenger sides. 1 of the dual pane window assemblies is separating from the other window
We have hehr windows on our class a rv that the frameless window adhesive has failed on three windows and possibly 3 others. One window the latch has failed also. The windows won't properly close and flap going down the road. We are worried about them flying/falling off as we are driving.
The driver's side window is a double pane gas sealed type. The double pane seal has failed and the window has become opaque. It has become very difficult to see through this window. From a safety stand point this failure is causing an inability to view the side view mirror on the drivers side.
A part of the locking mechanism on the only door on the rv broke, effectively trapping us inside the vehicle. The manufacturer (trimark) is aware of this issue and now manufactures the part out of steel instead of the cast part that failed. We were at a fuel station and parked.
