On certain fifth wheel trailers equipped with bedroom slide out rooms, the front cross-member connected to the hitch pin box may not be of adequate strength.

Source: NHTSA data as of September 22, 2026. Last refreshed Sep 23, 2026, 2:43 AM UTC.

Summary: On certain fifth wheel trailers equipped with bedroom slide out rooms, the front cross-member connected to the hitch pin box may not be of adequate strength.
Consequence: If overloaded, extensive use, added hitch weight, and/or road unevenness, stress on the c-channel could cause the hitch pin box to have crowning or stress fractures causing the upper frame to drop down more than one inch when connected to the tow vehicle. This could affect the steering capability of the towing vehicle increasing the risk of a crash.
Remedy: Dealers will add a 2" x 3" x 86" 11 gauge steel tube to the existing front cross-member and inspect/repair all welds, joints and structure of the upper frame decking. The recall began on April 15, 2004. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact sunnybrook at 574-825-5250.
Notes: Customers can contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

Has your Mobile Scout been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Mobile Scout dealer can also check your VIN. Recall repairs are free.
