A modular tow trailer assembly tows cargo behind a motor vehicle. A base assembly pivotally connects to a fork assembly. A hydraulic lifting cylinder moves the wheels downward relative to the fork assembly to raise the fork assembly into a towing position with the load substantially centered over the trailer's wheels. The tow trailer is readily partially disassembled for fitting within a cargo container and transporting within a cargo carrier in field conditions.
