Semi Casual Custom Trucks

Redefining What a Heavy Duty Truck Can Be

The GH-5 Grand Hauler is a fully custom luxury conversion built on the legendary Peterbilt 589 — one of the most capable heavy-duty platforms ever made. We take the raw power of a Class 8 semi and transform it into an experience that's as comfortable as it is commanding.

Premium leather, rear air conditioning, a built-in refrigerator, a 1,400-watt sound system, and seating for up to five. All backed by Cummins X15 power delivering up to 565 HP and 1,850 lb-ft of torque.

GH-5 interior — driver cabin

Premium Comfort

Diamond-stitched leather, rear AC, built-in refrigerator, 1,400-watt premium audio, USB/USB-C charging, dual 110V outlets, and spacious rear seating — engineered to make every mile first class.

Proven Performance

Cummins X15 engines producing up to 565HP and 1,850 lb-ft of torque, paired with 18-speed automated transmissions, a 240-gallon fuel range, and air-ride suspension for effortless long-haul capability.
