Towing question
 

I have a 2007 Chevy Impala with a 3.9L. The head gasket is blown and it needs to be towed circa 600 miles. Would this be possible with a 2011 Mercedes Benz ML350 4Matic? The owner's manual indicates the towing capacity is 7200 lbs.. I am thinking of using a UHaul car dolly where the front wheels are put on it. There is a full trailer option where the entire car rides on it. The concern here is the distance. Thank you.
