I have towed all kinds of trailers and loads for over 50 years. Lots and lots of miles. I could have borrowed a flat bed or even used my own enclosed trailer, but tried the U-Haul tow dolly. It was safe and it was easy. Sorry that you think something is unsafe that you have never or will never try. If tow dollies were unsafe, they wouldn’t be allowed on the road. Take a look at what’s rolling across our country on US-80 or US-70 – lots of tow dollies. Trailers are unsafe is not used properly.
