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

You have a pretty small Class A, front engine with a biggish rear overhang. Your tongue weight limit is likely around 500 lbs (matching a tow weight limit of 5,000 lbs) as is typical on those units. No car, golf cart, or anything else remotely street legal that meets the definition of "car" weighs 500 lbs. Just drive the thing a bit, you will get used to it. The only think to remember with a flat-towed car or a car on a dolly is don't back up, even a little bit.
