Patients may need dialysis. Kidney function often improves if the underlying disease is successfully treated. Abbreviated ATN.
Buying a tow dolly can cost  $1,000-$4,500, depending on towing capacity, size, quality of materials and other options. For example, the Roadmaster RM3477 Tow Dolly with built-in electric brakes sells for $1,600 -$2,000, and can tow a vehicle weighing up to 4,250 pounds.
Additional costs: Car trailers use two main styles of hitches, a receiver ball mounted on the rear of the tow vehicle or a gooseneck hitch. If the tow vehicle doesn't already have a trailer hitch, it can cost $100 -$850 to add a rear-mounted receiver ball or $400 -$800 for a gooseneck hitch.
