Tandem tow dolly

I've not seen a tow dolly with tandem axles. I've also not seen a tow dolly with a single axle and dually wheels. If such exists, I'd like to see it and see what it's used to tow.

If you want something with tandem axles, a tandem axle car hauler trailer, or enclosed cargo trailer, would be the way to go. You can put the whole car on the trailer, plus haul other cargo on the trailer, and the trailer has it's own brakes and lights, and can be easily backed up.

A link to what you are talking about might help. I am not finding much on "tandem tow dolly" on google.
