The cab cage is structurally sound but built as unobtrusively as possible. Ingress and egress are only slightly trickier than a stone-stock F-150. Once underway, one notices what's lacking: the typical creaks and rattles that surface when stock sheetmetal is pierced by tubing. Ron Mangus's talents are responsible for the upholstery that silences and civilizes the interior. Of course, without the quality metalwork that connects the stock sheetmetal to the 4130 tubing, there would be plenty of shakin' goin' on, but it wouldn't be quite as loud when covered by upholstery.
