I have an Acme brand EZE Tow Dolly for sale, I believe that it's about 20 years old. Tires/wheels and lighting/wiring were all replaced with the the last 3 yrs with LED lights. Dolly is equipped with hydraulic surge brakes. I have ramps and wheel straps to include with the purchase of the dolly.
 

The design of this brand tow dolly is meant to be light weight and simple. You can very easily move it around by hand. Also if you tow a car with a smaller motorhome lighter weight is important. I used this behind my motorhome and also to haul a car around with my truck. I think the tow ratings are 3500 axle weight on the dolly and 5000 pounds total weight. It's served me well but I don't use it anymore.
