A trailer is self-propelled via a powered tongue jack and includes a lightweight, high-efficiency asphalt heater. The trailer is moved long distances, such as to and from work sites, using a towing vehicle, in conventional fashion. When at the work site (or storage site), the tongue jack is lowered to support the trailer in a generally horizontal position, and, by virtue of a powered jack wheel, can be used to position the trailer easily, quietly, and confidently in either the forward or reverse direction.
