We flat tow our 17 MKZ hybrid. It is to simple to flat tow that I wouldn't dream of dealing with a dolly. My wife hooks and unhooks the tow bars while I put in or take out the brake box. I have seen way to many people lying on the ground trying to strap tires to tow dolly that I can't see how that is better. Plus a lot of campgrounds you would have to have an extra large site to fit it all on. Once you unhook the tow bars they fold up to the MH and you are done. No manhandling a tow dolly somewhere.
