Sounds like tow dollies have advanced like boat trailers, and can now be had with a brake actuator that has an electrical solenoid on the brake (fluid) line, that closes when receiving a 12V DC signal provided by the tow vehicle backup lights. The solenoid keeps fluid from flowing to the dolly brake cylinders.Hmmm.....surge brake tow dollies can be backed up? Not the ones I have towed with!!!
There is a pin you have to put in the hitch to "LOCK" the surge brake out to back up on about any trailer/dolly with surge braking.
