This International Payhauler off-road tow truck by Wayne Calder was built from Ertl's International Payhauler dump truck. Although Ertl sold this as a 1/64 scale model it can be converted to 1/85 scale with simple modifications. The cab needs to be cut down by 1/16 in, the wheel track needs to be reduced and the dump bed lowered. The tow truck model was kitbashed from a variety of sources. Shown below with a modified Ertl dump truck model.
