A trailer with mechanically activated dolly legs includes a trailer body having a front towing end and a rear end. Ground engaging support wheels are positioned at the rear end. Means are provided for attachment to a tow vehicle at the front towing end. Dolly legs are positioned spaced from and underlying the front towing end. The dolly legs are housed in a housing and are movable relative to the housing between an extended position and a retracted position. At least one air bag is positioned between the dolly legs and the housing. The air bag is adapted to move the dolly legs from the retracted position to the extended position.
