the dolly i used had a frame and axle that was below a floating subframe which did exactly that.FLOATED ON TOP OF THE AXLE...for cornering and making turns..i had never seen one like this before..it even had the sticker on the hitch telling you do not back it up...very wacky..it worked but very hard to put the car on and DEFINATELY could not back it up..cause the floating subframe would go one way while the frame and axle would go the other...and by the way, i own a boat for the past 6 years so i know how to back up a little trailer..can someone help me out with this.anybody seen the tow dollies im talking about?? ..good luck.
