A licensed set-up contractor moves and sets a manufactured or mobile home. Some haul and set; some haul only and hand off to a setup crew; a dealer's price often includes both.
Short answer: Moving the home is a permitted highway move — the transporter tows each section on its own axles with escorts and permits. Setting it is the licensed part: blocking the home on piers and footers, leveling, anchoring to the state installation standard, joining the halves of a doublewide, and connecting the crossover duct. In North Carolina set-up contractors are licensed by the Office of State Fire Marshal, and the licence can be looked up. Ask whoever quotes you which of the two — transport, setup or both — the price covers.
