Interesting discussion because I just came back from a 3 week trip without a toad and am definitely getting one hooked up. I have a 2016 FR 30DS and will be pulling a 2010 Fusion Hybrid four wheels down. The car is capable. I think I know what parts are required, but I have a question. Is an auxiliary braking system necessary? I'm not asking about the legal issues, but I've spoken to some folks in campgrounds that tow and they say they don't use or need one.
Also, does the inertial type supplemental brake meet the legal definition?
