Example complaints
One per model year, chosen for length and detail. Personal details are removed. They are consumer reports, not findings.
2014: “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. We had to climb out a window with tools to force the door open.”
NHTSA complaint #11078987, filed 2018-03, 42,000 miles2013: “A friend on an rv tour let me know that my running lights on the side of the rv blink on the right side when you turn on the left turn signal and on the left side when you turn on right turn signal, they are wired in reverse. I have contacted thor and they refuse to correct the safety issue even though there is a possibility of this causing an accident.”
NHTSA complaint #10679891, filed 2015-01, 7,000 miles2017: “While driving the rv, the window above the sink separated. The window is double paned. The outer glass pulled away and was flapping, causing the interior glass to also start pulling away. We were on a stretch of highway that was busy with trucks, approx 6:30pm (dark), 2 lanes eastbound I-40 in california. There were no exits for 20-25 miles after the incident began. The window continued to bang and pull away the entire drive. The pull from the wind threatened to completely separate the window assembly from the rv. …”
