Important: Roadmaster 2026 safety recall - check tow-bar serial number

Roadmaster's October 20, 2026 safety notice (NHTSA recall 26E069) identifies certain 576 units with serial numbers 620148–622899 for a T-bolt retaining roll-pin inspection. Not every unit in this model is affected: inspect its serial number and the T-bolt assembly per Roadmaster's official recall instructions. A missing, loose or displaced roll pin may cause tow-bar separation; do not tow if the roll pin is not fully seated or has moved more than 1/16 inch above its hole.

The serial number and recall status of a particular inventory unit must be verified before shipment or use.
