The RoadRunner HD features a rigid frame with large 14" x 4" tubes on 52', 48' and 42' models and 12" x 4" tubes on 36' and 30' models.
The tricycle front wheels facilitate maneuvering for tight turns, and the tongue rotates fully under the frame so less space is needed during storage.
The tongue is length-adjustable from 57" to 81" to match individual towing needs and telescopes up to 24" for ease of hitching.
