The mod uses interior parts from the Mack Superliner by RTA, specifically: cabin upholstery and cabin body models. The rest of the interior is built from scratch, including: dashboard, all gauges, switches and knobs, stickers, steering wheel with column and attached levers, gear shift lever, heater and seats, roof hatch, mats, and pedals. All animations are also made from scratch. No textures from the Superliner are used. The number of triangles in the upholstery and cabin body models has been significantly reduced.
