The trailer dolly is characterized by an axle mounted on a pair of wheels. A dolly frame height-adjustable trailer hitch that receives a primary or a secondary trailer. The adjustable hitch on the trailer dolly allows horizontal leveling. A shock-absorbing spring is fitted between the axle mount and the dolly frame for cushioning the dolly frame on the axle mount as the trailer is towed behind the towing tandem trailer.
