What toad is small enough to carry on the back of a Class A?

I DO appreciate the info from everyone. I also understand that we can't pack a car on the back of our Hurricane. I knew it was probably impossible. Since we just purchased a pretty small car from my son (a 2006 Volkswagon GTI), we will be trying to get the equipment to tow it. Would prefer the dolly.

As a side note, I absolutely LOVE the Smart Cars. Look like little roller skates. Hopefully we can get our other tow vehicle, the Nissan truck, sold soon!

Again, thanks for all of your input. A
