Say goodbye to the hazards of negotiating your gear onto a roof rack. The RACKandROLL Trailer carries up to three times the weight of a roof rack, yet is light enough to roll around by hand. Simply unhitch the Trailer and you have a lightweight hand cart to move your gear wherever you like. Its large 16-inch Alloy Wheels roll easily over bumps and make transporting your gear on and off the road smooth and easy.
