Any of you ever use a 5th Wheel Dolly like this?

Is THIS what you are thinking of?

I think I was behind one the other day, when he was trying to merge on the freeway:)

Seems to work fine on the small trailers; does it work on my toy hauler at 8 tons empty and 3500 pounds on the pin?

Well, I need to find a device like this where I can just buy it & use it.
Then all my issues will be solved & I can feel safe about buying my 5th wheel.

I've never used one, but did talk to a guy who was towing with one. He loved it and had a bed rack on his truck with his side x side on it then an aux diesel tank and fresh water tank under a deck, in his bed. He said that it actually turned wider than it did when it was hitched in his bed =and= has an extra brake axle.
