Abstract: A portable cart is described which has an extendable base to elevate the cart to a proper height to mount in the receiver or a trailer hitch. The extendable base is retracted, pulling up the cart wheels. This allows the cart to be carried by a vehicle. Once at the desired location, the vehicle is parked. The extendable base is extended to support the weight of the cart, which is removed from the vehicle. The cart may then be lowered and wheeled to its use site. The cart may be designed to hold baseball equipment, act as a sports training cart with first aid supplies, or material spill cleanup equipment. It may also carry food and supplies for catering, contain an outdoor mobile grill, act as a service company cart, a construction cart, an equipment cart for first responders, a pet show cart, a trade show cart or employ armored to carry ammunition and military supplies.
