Towing Issues: Towing a car, car dolly, ford escape

Question
I wish to tow a car behind my motor home. We have a Ford Escape and a Grand Am. Which would be the best to tow and what are the advantages between a T Bar or a Car Dolly

Answer
Well as a rule, tow bars require some vehicles to be modified to be able to be towed with all wheels down, whereas a Car dolly can be used on a wide range of vehicles...

Best answer would be the dolly as if you traded off either car you could still use the dolly depending on what vehicle you are using...

Only draw back with the dolly is its size.. They do tend to be in the way at times..
