I've towed my FWD 2012 Prius on a Roadmaster tow dolly with no problems at all. Although the tow dolly complicates things around a campsite, and storing it in the winter, it is easy to drive the car up onto the dolly, put the vehicle in park, no emergency brake, and strap the front wheels in and go. It's best to check the straps every stop and tighten if necessary. The tow dolly has electric brakes, so no external braking system is necessary, just an electronic brake controller in the RV to adjust the braking sensitivity and response.
