This is an Asphalt Double chute Hot Box trailer...which typically carries 4 tons of hot asphalt to a job site and tilts. These are normally hauled by heavy duty pickups or small truck tractors like a Peterbilt 385 etc. This will tilt, but I didn't include hydrauiics to keep the cost and complexity down. There is two hitches, a pin and a hoop, so you can use either for your particular hauling rig. No, the doors on top or chute doors don't operate. These are used by DOT and city/county road departments etc. Should there be a question or concer, contact me via the designer link or via email to firstname.lastname@example.org
