• a first fender coupled to a first side of the dolly frame and a second fender coupled to a second side of the dolly frame;
• a first-bumper frame comprising a first-sliding bracket and a second-sliding bracket spaced apart from the first-sliding bracket;
• a second-bumper frame comprising a third-sliding bracket and a fourth-sliding bracket spaced apart from the third-sliding bracket, wherein the first- and second-bumper frames are each coupled to the rear section;
• a tongue with a first member, a first support arm, and a second support arm, the first member comprising a sleeve;
• wherein the first-, second-, third-, and fourth-sliding brackets each include a first wall with a first aperture, a second wall with a second aperture, and a base interposed between the first wall and the second wall;
• an axle;
• two ground engaging wheels;
• an adjustable trailer hitch comprising a second member, the second member may be positioned in the first member and extend therefrom;
• the adjustable trailer hitch fastens to either a vehicle or a primary trailer, the adjustable trailer hitch comprising a bracket;
