Toad is just a nickname for a Towed motor vehicle. And no towing a toad isn't the same as a trailer in a couple of areas. The toad is usually pretty small as compared to the tow vehicle so you don't have many sway issues or things of that nature from the toad like you may from a trailer. The biggest different is you generally cannot backup with a toad. So you have to be very careful about getting into spots that you cannot pull forward out of. I have twice got myself into those spots and had to go back and unhook the toad to get out.
One of my main reasons for going with the Class A versus the trailer is I really didn't want to have a monster truck as a daily driver. My toad is a Dodge Dakota and it's a perfect size truck for me. Small enough to be towed by the motorhome and small enough to fit in most parking spaces, yet still has 4x4 and a truck bed to haul junk around and be used as a daily driver. And it fits in the garage.
