The Royal is custom-designed to match the specific model of your truck. The fit, color and styling are so alike, the truck and cap look as if they were built together. SUV-inspired side windows have twist-out rear vents with screens. The rear door is frame-less and features curved glass with rotary latches and teardrop handle. The Royal has lots of great standard features, value, and looks. All molds feature a trim-less edge and skirted sides to conceal the bed rail caps.
