As discussed in other threads...
Uhaul rents one type of Tow Dolly nationwide.
They all have NO Brakes.
A few years ago...there was a lawsuit regarding an accident of a vehicle pulling a Uhaul Tow Dolly. The NO Brakes was part of the lawsuit.
I think they settled out of court.
Today, Uhaul still rents Tow Dolly’s without brakes.
So it’s always entertaining to read all the discussions on this and other RV forums about Toads & Tow Dolly brakes vs no-brakes.
