Thank you DouglasC for the information on the Fusion and your tow dolly incident. It sounds like you now prefer the four down method of towing. That is what I am also familiar with but with the two vehicles I currently own (2012 Escape and 2011 Ford Fusion) and the transmission problems I have been reading about I am reluctant to set up one of the cars for towing and then have a transmission problem that Ford will not cover.
Lately we have been seeing a lot more two wheel tow dollies behind motorhomes and thought this might be a way to tow a car as an alternative to four down. The number of cars that a towable four down keeps dropping from year to year. This year (2014) there are only 75 new cars and trucks out there. Thanks!
